Hey! I just found you're channel, way to go! I really am enjoying everything im seeing, so very well done . Im putting you up there with chemical force its actually refreshing to see the career and hobbie ive been addicted to as a very young child playing mad scientist by dumping a bit of everything that was in my aunt's bathroom closet onto the toilet bowl! Cleaners, antacids, aspirin, toothpaste, (for texture! ) and it pains me to say 😢 her medicine cabinet ! Where her prescriptions were, holy shit i didn't dump all of her meds down into the cauldron of herr professor dopeinstupid . And yes a really bad reaction had taken place when I added a final ingredient! Yes a little dab of draino crystals had started to fizz really loud like, and then came the fumes! Oh well kids got to love em!😅
I used silver nitrate and sodium citrate to make silver citrate, which resulted in a clear solution which produced white crystals. Is the silver reduced here because of the heat and/or stoichiometry? I've made silver nanoparticles with a few different methods, but mostly with electrolysis, producing a range of concentrations up to completely opaque. At a certain concentration, it resembles anti-freeze. I didn't know about the infrared properties though, that's pretty interesting. Thanks!
The silver should be reduced in every combination, but the low concentrations and stirring lead to the formation of the round particles. The heat is just to increase the speed of the reaction. If the concentrations are higher, it's possible for one or both of the compound to crystalize on cooling or large crystals of silver are formed as a precipitate. Electrolysis to make silver nano particles sounds quite interesting. Are these spherical particles? I wonder how they form at the cathode and are removed. I would have guessed, that there would always be just crystals forming in electrolysis.
@@RaExpIn @RaExpIn I just followed some colloidal silver methods. I've used glucose and cinnamon extract as capping agents, using low current and strong stirring. I cut a silver round in half for the electrodes, and used a small timer and DPDT relay to alternate the anode and cathode a couple times a minute, so I could wear on both halves evenly and avoid contamination from other metals. For the citrate, I followed _"Synthesis and Antimicrobial Activity of Silver Citrate Complexes"_ I use the citrate as a deodorant.
I request you to show as the COD measurement process according to APHA5220D. with reagent A and B making as well as the use of the spectrophotometer. is it possible?
Good demosntration of rayleigh scattering,gotta show this to my kids when they ask me why the sky is reddish at sunset😊

I wonder if this works with copper.
I guess this would work, but only with hydrazine or some other exotic reducing agent.
@@RaExpIn Ascorbic acid do reduce copper, but it will not be colloidal. The particle size is way too big.
