THANK YOU SO MUCH PAUL YOU HAVE SAVED MY LIFE
I have been taught that you shouldn't pour used chemicals back into their original container, as it would risk contaminating the rest of the chemicals
yep same
Our teacher told us to put it back and I know it's safe because the concentration of the solution wont contaminate
thank you paul🙏🏾
The noises coming from this experiment are pure ASMR
Got the test tomorrow, good luck boys
@@shaaravguha3760 you too mate
Good luck
@@shaaravguha3760 and to you lad
It has guided me perform my practical in the igcse curriculum in Somalia
Cheers paul
Cheers Paul!
PAUL ROBERTS AAAAH
Luv u Pearson
What voltage value from power supply should i use it for magnesium chloride electrolysis???
I LOVE YOU PAUL UR SO CUTE
Wow thanks for explaining
The pink colour, am in/correct in saying that it’s the copper in the solution attaching itself to the graphite? Which is basically saying your “electroplating” a part.
PAUL YOUR A CUTIE
Good, interesting, clear video. Two questions: 1. What electrical resistance would you expect through the electrolytic cell? 2) If the resistance is very low, should you use a resistor in the circuit to reduce the current? Thank you.
aired, lol
Me just learning this now when my exam is in an hour and 30 mins
Franklin was here
Why don't you use a laboratory power supply? It's much easier.
great vid! you look tight
AWESOME
Wow.
Why bhasky??
😅
Really theory and no practical
Questions (please answer):
1) Why do you use an ammeter in the circuit?
2) Why is it necessary to clean the copper electrodes with emery paper before using
them?
Why is he sitting down? In practicals my teachers always say to stand up.
Paul is a wheelchair user, students would usually be required to stand for a practical. :)
@@aliyah9468 If he is a wheel chair user, this means he is not fit to conduct the practical, which is a safety hazard. They should off got someone else to do it :)
edit: Also, I am aware that students are required to stand for the practical. I am also aware (as I have eyes) that Paul is a wheelchair user. Thank you for adding absoloutely nothing to this thread
