I've been playing with making TEOS. I've been trying the Al2 + S3 -> Al2S3; 2Al2S3 + 3SiO2 -> 2Al2O3 + 3SiS2 technique where you just dump the resulting SiS2 into absolute ethanol to get TEOS. These fusion reactions are fun and challenging. One thing I found was that using a small graphite crucible is a huge win. You actually get better and more consistent yield if you heat the crucible to keep the reaction products molten for a little while longer after the self-heating starts to drop off.
wow my chemistry teacher made this experiment today and i asked if she knew it from nilered and she said yes .....i think you have teachers watching you
And that is remarkable because....? You have one single teacher that you know of that has watched this and from that you get that there are teachers (plural) out there all watching this? That's a logical fallacy that would make a creationist cringe.
Michael Goodness, you are disproportionately angry for something so incredibly minor. My friend, that was not a fallacy at all. A fallacy, by definition, is "Invalid, or otherwise faulty reasoning". Now, I understand that anecdotal evidence is not equatable to empirical evidence. But there is still merit to it, assuming it actually happened. Now, there is no merit to hypocrisy. And it is hypocritical of you to catch this person for 'fallacy' while you are employing fallacies yourself. I will explain to you exactly how you are commiting a fallacy; by claiming this person asserted the claim that many, or even all teachers watch NileRed. This person very well could have been talking singularly about their teacher in an informal manner, reffering to them as 'teachers' because it is less effort and more cohesive than saying 'A teacher of mine'. You are refuting a claim that was not made by intent, and therefore have refuted a claim irrelevant to the conversation. By refuting a non-relevant claim in place of a relevant one, you have commited a strawman fallacy. And even beond that, you, by refuting their "claim", now hold the burden of truth. You seem to oppose the idea that Teacher(s) watch NileRed, so now it is up to you to prove that no more than one teacher watches NileRed. Good luck with that. Argumentation is a skill best earned with practice. But hypocracy is a very powerful destructor of progress. You would be best to avoid it.
My first thought was making hydrogen sulfide and then you mentioned it :) When this reaction is done, people often forget that this is a good way to use it further.
You are right. I actually had no idea when I first did the experiment. I had to search a little about the final product to find out that it was actually useful.
@@Ormodius3751horseplay in the lab is a no go for me. There are hazards beyond poisonous fumes, corrosive chemicals, and flammable materials. Lab personnel use a lot of glass and porcelain which can break and cause injuries. Most school and university labs are equipped with natural gas lines for the Bunsen burners so an explosion hazard is always present. It’s not worth the risks for a few laughs at someone else’s expense!
Trevor Squires since the expansion of heat goes from center outward, the watch glass will heat up from the center outward. this will cause the energy to move through cooler areas at an extremely fast rate and this disrupts the dipole IMAs of the glass atoms. this rapid thermal energy expansion shatters the glass since the kinetic forces surpass the capacity of the IMAs.
@@katiedonovanAlt Pyrex is not more heat resistant, it is however more tolerant of quick temperature changes. Pyrex actually had a lower melting point than glass
Ball mills are great - and I use them occasionally for grinding individual elements or some compounds - but would not usually use a ball mill to "grind and blend" - So for example, you could make sure your willow charcoal was airfloat with a ball mill - and then seperately - your KNO3 and sulphur before blending. I am VERY surprised to find that professionals would use a ball mill to MIX an explosive compound though.
Iron sulfides synthesized in the described manner will not undergo pyrophoric oxydation. Pyrophoric mackinawite, FeS; greigeit, Fe3O4; or (due to aging of the aforementioned species in presence of sulphur) ultimately pyrite, FeS2 is often encountered in sour gas systems upon reduction of oxidic corrosion products with H2S, thus it forms under anaerobic conditions. The specific surface area is crucial for the product to be considered pyrophoric.
In the video, I think you ought to have mentioned that the stirring rod didn't shatter because it's made of Pyrex, a very heat-resistant glass. Is that right?
Pyrex is just the brand name for borosilicate glass. In general, borosilicate glass isn't resistant to heat, it just has low thermal expansion compared to other glass. This means that when exposed to large differences in heat, it is less likely to shatter. The glass rod can handle so much heat because of its size and shape. When exposed to the heat, it expands in a way that doesn't stress the glass enough to shatter it. Unlike the watch glass which shattered extremely readily. I honestly don't know very much about this though.
Pretty much any glass can be taken to red heat (and beyond) if done carefully. With suitable eye protection and at your own risk (etc etc), playing around with a few bits of broken glass tube / test tube / thin sheet glass (old light bulbs) and a blowtorch can show you that, done right, you can melt and bend glass easily enough. I have managed to bend glass tube with nothing more than a gas cooking hob - though admittedly it is barely adequate. Get some good protection for eyes and skin - and, at your own risk of course, have a play :)
I thought to myself last night as I was laying down to sleep, on what would happen mixing FeO + S together in an oxygen free environment. I'm bound to try this and it will likely result in nothing exciting, however, since FeO is pyrophoric and reacts readily with oxygen in the air, I'm thinking since sulfur shares chemical characteristics of oxygen and may produce iron II sulfide just by combining the two chemicals.
This could be used as a precursor to sulphuric acid. The iron sulfide can be reacted with hydrochloric acid to produce hydrogen sulphide which can then be combusted to form sulphur dioxide. This sulphur dioxide can be reacted with oxygen in the presence of a vanadium (V) oxide catalyst. This will become sulphur trioxide which can react with water to form H2SO4 (sulphuric acid); or more commonly, the sulphur trioxide can be reacted with concentrated sulphuric acid to form oleum (fuming sulphuric acid)
Кирилл Рагузин Yeah, it wouldn’t be practical to convert the iron sulphide into sulphuric acid because, as you said, you could just use sulphur. However, iron sulfide can be found in nature so, when it is collected, instead of separating the iron from the sulphur to make sulphuric acid from that, you could make it directly from the iron sulphide. But in this case, synthesizing sulphuric acid directly from sulphur would be more practical than iron sulphide (especially in smaller scale laboratory conditions)
Okay... I remember we made a compound by hearing iron and sulphur powder in a chem lab in high school. It was in 8th grade or something and we did so by heating the mix in a test tube on a bunsen burner. I don't think there was any glow or that much heat from the reaction. A gas did evolve, (it might have also been acidic I don't know exactly) Can anyone help and tell me if we did the same reaction? Because the way he showed it, it sounds quite dangerous but what we did was very tame.
The Reaction itself is just Fe + S --> FeS. There is no oxygen consumed in the main reaction. Due to the high temperatures some of the Sulfur just reacts with oxygen in the air, so grinding it und e.g. argonatmosphere would still ignite the mixture, it also simply stops the sidereactions and you could possibly use a 1:1 ratio of iron and sulfur.
Could you make a video on making Zinc Sulfide? I've been trying it several times, but can't manage to get it right (luminescent). Maybe it's something to do with the ratio.
Maybe you find some time to demonstrate pyrophoric oxydation by reacting moist FeO(OH) with H2S in absence of O2 one day. If carried out at elevated temp. (some 100 °C) the resulting FeS2 rich product should catch fire as sooo as it contacts air.
I do this as a demonstration every year, but cannot get the reaction to self sustain. I use a copper plate in my fume hood. Typically I use 7 g of iron and 4 g of sulfur. This year I have tried warming the plate ahead of time to limit cooling of the reaction, and I have tried gently packing the reactants and leaving the reactants loose. Do you have any other advise?
Quartz is good for about 1600 c and I am not convinced that this reaction would exceed that. Beyond that, alumnium oxide crystal (as per some watch glasses) is good for just over 2000 C. Higher than that and I think you might be struggling with rare earths but I have no data on their melting points.
I must have crappy iron powder/sulfur. I need a jet lighter to ignite it and use a coffee grinder to powder the iron sulfide, all of which the video says you shouldn't do.....
+Nile Red If FeS is pyrophoric, how come it is not burned in the process of preparing it? The amount of heat is released, should convert FeS to Iron oxides.
That's a good question. I assume its because the iron quickly reacts with the sulfur in an environment lacking oxygen. It then fuses together. so the inside still hasnt really been exposed to air. If you crush it up, the inside will now be exposed. This is just my assumption though.

how is your glass stirring rod different to that glass dish that broke?
+Pagan Min Perhaps, since the glass stir rod was heated before the reaction, it was less vulnerable to breaking from heat shock than the watch glass?

Could you make one about obtaining pyrite crystals?
I dont understand why the sulfide is marked as a liquid. If it is in form of powder shouldn't it be solid?
the reaction happens after the sulfur has melted. Solid-Solid reactions are usually very very slow.
This is technically a thermite reaction
Is there a conductive rod that can heat up or become zooming electrons from touching the powder but not ignite the reaction? Copper or something?
have you ever tried to purify the iron II sulfide? say with .4 mol H2SO4
