Fermentation in Yeast Experiment

Dear viewer/subscriber, if my videos helped you a lot (maybe you aced your exams as a student, or you won the admiration and full attention of your students as a teacher, or you got your techniques right as a hobbyist), then its my humble request if you could take a moment to consider supporting me on anyone of the following platforms:

Patreon members and channel members will get exclusive access to members-only perks and added benefits such as free PDF notes, Q&A doubt clearing chat sessions, Experiment video requests, Member shoutouts, Behind the scenes and more.

Or if a monthly payment is not convenient for you right now, you may instead consider supporting me with a one-time thankyou gesture by clicking on the SuperThanks Icon below my videos next to the like dislike buttons. Pay the one-time-only amount that you feel is worth the help and benefit you got from my video. Apart from Subscribing to my channel and sharing it with friends, colleagues and students, you valuable one-time or monthly financial support will really help sustain this channel and make it possible to come up with even more engaging and educational content.

Creating experiment videos involve hundreds and thousands of dollars put into procuring the requisite chemicals, equipments and labware to make a single video. To say that i will be extremely grateful for your support would be an understatement.

This was a very beautifully and simply explained video😍😍Just know that you have really helped someone in the world and this person really appreciates it !!

[kshitijsardal]

I was not able to undretand this experiment from my book...This video made it Super clear!!!!...🤩🤩 Thank you

[nontandolembethe]

this video helped me a lot, everything was specified. thank you so much.

[paranshizaveri]

hi, great video !! super helpful:) i have some questions and i was hoping you could help. how do we know when the reaction has come to an end? also, to measure the rate of reaction we just count the number of CO2 bubbles during the reaction time right?

[icecreammonster]

I love this so much, but i have a question. What would happen if you didnt use any oil but only the yeast?

[Flootyy]

is water needed to make any bubbles at all, or can a solid mixture still produce a small amount of CO2?

[sairamprasath]

I have 3 questions- 
1. Is there a way to measure the ethanol produced in the reaction? 
2. Also, how do we know that the ethanol has not gone to the other(Smaller) test tube? 
3. After the lime water turns milky can we connect another cork with a condensation tube and condense the ethanol produced by letting in cold water?

[inkton]

What is the purpose of using boiled water Vs just normal water?

[portiasetulo]

Suggest a suitable control for this investigation to show that it is the yeast in the flask that is responsible for the results that you observed.

[ashmitavsood]

What exact volume of glucose, yeast and lime water did you use?

[cameshaboreland]

What does the froth on top of the yeast solution suggests?

[Asra_Fareed]

I was unable to do the practical thus i watched this vid, i would like to ask... what did the sides of the (glucose solution with yeast) test tube feel like after a while ?

[pan_ching]

Can I ask ...What is the effect of yeast to lime water? how does it affect each other??

[noralas]

hi I have a question regarding this experiment.

can yeast utilize all of the sugars equally well? I just wanna know

[danbleil]

Hi, I am designing such an experiment and need to calculate the rate of respiration of the yeast. What do you think would be the optimal time for the yeast and sugar to react?

[sinahakimpour]

Hi there just a quick question. Would it be ok to use just water instead of lime water and measure the change in liquid to determine how much co2 was produced?

[garushiverma]

Hii there
I have a question
How long does it take for this change to occur

[mikkaddescaya]

Hello, what is solid that forms during the fermentation of calcium hydroxide?

[ogaufi]

After 60 minutes, there were no bubbles coming out of the delivery tube...suggest a reason?
