Hello students.

Now in this question they are asking why is there a need of ph indicator in case of fermentation processes? first of all, let us understand what ph indicator means.
00:13
Ph indicator like the name suggests you can find out the ph by adding certain chemicals that act as indicators.
00:21
For example, you can add phenofstylene, right? what is it? it is a substance that will give pink coloration to the solution if the solution is acidic, right? so in this case, the ph indicator is helping with that.

But why is it needed in case of fermentation? now, what happens during fermentation? basically, fermentation involves the use of microorganisms, right? now, when there are microorganisms, you never know what happens, right? the control is over microorganisms.
01:02
Yes, you do give the required nutrition for the fermentation to occur.
01:07
But it depends on the microorganisms that take up all the nutrients or whatever it may be.
