Usually the older videos despite poor quality do a good job I'm so happy to find a more recent video which does the same job Thank you. You made online learning that bit easier
A very good and best teacher also telling theory with practical .I just loved this teacher Sir you are a very brilliant teacher Your teaching method is awesome . When you are teaching I am just feeling that experiment but in my room like this experiment was happpening in front of me .🤩
Sir may i ask you a question for my thesis. Why magnesium sulphate heptahydrate causing white precipitation does look like a gel/cloud and sometimes crystalline when it dissolved in 30%w/w of ethanol solution? So that salt is very poor for induce aquous two phase separation layer between ethanol and water. There is a limit literature about that :(. Thank you
Awesome video! Quick note: At 5:24 you may have misspoke, you said there was no "chemical reaction" when I think you meant to say there was no "precipitate". Hope this comment helps!
That's true! Copper can be more than one colour depending on the form it is in. Think about iron; it can appear black, grey, or even shiny in its pure form depending on the level of polish it has. When it reacts with oxygen and water, it forms iron (III) oxide which is red. In solution, copper is often a nice blue colour, but when excited directly with a flame you will see a green colour. Copper corrodes to make a green patina (like European copper roofs, or the Statue of Liberty in America).

THIS IS MY TEACHERRRRRRRRRRRRRRRRRRRRRRRR
Finally my teacher found a video that wasn't filmed in the 1800s
😂😂
😂😂
Well actually, if I'm not mistaken, the video camera was invented in 1918

Best channel for learning practical chemistry
i love "periodic videos"
YOUR EXPERIMENT WAS VERY GOOD 👍AND YOUR EXPLANATIONS ARE VERY
GOOD❤👍
This saved my life thank you 🙏🙏

Thanks a lot it helped me in my studies 🌻💛🌿..
Wonderful video
Excellent video.
Is there a way to prevent or counter precipitation?
Thank you
Thank you so much 😊
We want the explanation of all science lessons plzzz if possible make the video and good explanation keep doing 🎉❤❤..... Love from India

Teacher can u make new videos about chemistry.
I was searching for this thq
Yeah, it might have been a tad more dramatic to add drops of copper sulfate to see precipitate form in a beaker of clear sodium hydroxide.

😂😂😂 sotti
I am watching your video in further👍
Thank you so much

U said coppers’ colour is blue, I sent it green, I learnt it from the flame test….

Hopefully I learned this ppt reaction..... 🙂
Sir perform black ppt reaction
basics was here
My teacher sent me here? Who else?
Me too
Me three
Very good video
So these reactions are irreversible?
Make more
Chemist
Oi
3rd year chemical reactions
Teacher can u make more new videos
pov : we all here cause of school
True that
" Pov " means ??
DOCTOR SVITLANA is the best
where is my fucking purple or the red reaction😤😤
so one solution is grabbing the other and saying "we are THIS now"
Watching this for science class anyone else??
basics was here
Oi
I`m here because of my chem teacher :v
