you'd need to start with (somehow) conditions with no oxygen in the tube. but you'd do the experiment without the soda lime, and so measure the volume of CO2 given off, ie how much the fluid in the tube moves AWAY from the respiring organisms.
1. nothing: there's no organisms respiring and so don't affect the gas composition in the tube. 2. nothing: respiring organisms absorbs as much oxygen as they evolve CO2 (and no soda lime to absorb the co2) but this is all about the relative difference created between TWO tubes in parallel. so the question of one tube is kind of moot. it's always in comparison to whatever's going on in the other tube as well: that's what affects the movement of the liquid in the u-tube.. hope that helped.
how do we analyse the results...so measure how much the fluid has moved??
Excellent demonsteration !
What a life saver, thank you👍
Glad it helped!
When doing experiment for anaerobic respiration should we use soda lime since it absorbs co2 and will prevent pressure from increasing

Thank you.
what a fluid is best to use ?
How are you Dr Bhavsar! Long time no see!
Sir, how to calculation the result?
What formulation u use to calculation the result? 🙏🏻 thanks
Great👍
How can i clean the manometer after the experiment
1) What would happen if you had a tube with only soda lime and no organism?
2) A tube with living organism but no soda lime?
1. nothing: there's no organisms respiring and so don't affect the gas composition in the tube.

Where's the results table?
wht organism u r experimenting with is it tiny earthworms ?
maggots.
Hello Sir,
May I have your email id?
This is Sabyasachi Chatterjee, A Level Biology faculty.
Why do we not close both the taps?
this is explained in the video 🙄
sooooo useful XD
this guy has merch wtf
