Which of the following is true? a). an indicator is not ph sensitive. b). the equivalence
question:
which of the following is true?

a). an indicator is not ph sensitive.

b). the equivalence point is where the amount of acid equals the amount of base during any add-base titration.

c). at the equivalence point, the ph is always 7.

d). a titration curve is a plot of ph vs. the base)/[acid(info) ratio.

e). none of the above are true.

B). The equivalence point is where the amount of acid equals the amount of base during any add-base titration.

Explanation:

Equivalence point -

During the process of titration of the neutralization reaction , like acid - base reaction .

In the titration process , the equivalence point is the point , when the amount of acid is equal to the amount of base .

In indicator used for th process is pH sensitive ,

It is not always necessary to have pH = 7 at the equivalence point ,

The titration curve is plotted for the pH v/s base .

Hence , from the given options , the correct statement is ( B ) .
