Hello students, let's discuss the question.
00:02
So in this question we need to indicate the false statement about ph indicators and their uses.
00:08
So let's start here.
00:09
The first statement is a ph indicator suitable for titration of strong bases with strong acids cannot be used for titration of strong acids with strong basis.
00:21
So this is the first statement.
00:22
So here we can say that this statement is totally false.
00:28
Why? because we can then we can use the indicator indicators suitable for titration of strong with strong acid for the titration of strong acid with strong base.
01:03
Strong with strong acid for strong suitable for titration of strong acid with strong base so this is point this is point because at equivalence because at equivalence the change in the ph for the strong acid the change in the ph for strong acid or strong base we can say strong base titration or titrant titration is significant even after addition of small amount of titrant amount of tightrent so here we can say that first option will be false.
03:01
This is the false statement and this will be our correct statement.
03:05
Now let's see the second.
03:06
Second says the ph indicator always contained at least one acidic group that can be deprotonated to form a differently colored conjugated base.
03:16
So here we can say yes, this is a true statement.
03:19
So here we can say that b, this is a true statement...
