Because of you guys I cheated my whole project and hopeefully i get a good mark pray for me lol

[msho]

What is gas produced in the foam in the reaction?

Thank you so much, such an incredible video

May I ask main role of the pH buffer 7 in this experiment?

[timothy]

What happened in the test tube to produce the foam?

[dinakhouryy]

Guys plss answer me why did you add the ph buffer if we're just testing temperature not the ph level

[leeshawhiting]

i don't have access to the buffer solution, can i create it?

[SurpriseMabinane]

What is the hypothesis of the investigation

[Nobody]

if anyone can respond ASAP, why are they adding in the buffer solution? they aren't recording pH..

Ma'am answer please if I dehydrate potato will it loose its catalase enzyme?

[liahuntress]

I'm doing the same experiment at school but we're using detergent to be able to see the foam better. Is it needed in the experiment?

[tp]

Can this be done without the ph buffer?

[lanabalqa]

Hi,

What is the purpose of using the pH buffer? How does it help and what does it do in this experiment? And if I want to have a controlled experiment what should I do?

Thank you for the video it is very helpful!
