Compounds X and Y have the same pH at the equivalence point of their titrations with the same base solution. The pH at the equivalence point for compound X is approximately 8.5 Compound X is more concentrated than compound Y. Help Compounds X and Y are both strong monoprotic acids

Explanation / Answer

The correct option is statement 3

THE PH AT THE EQUIVALENC POINT OF COMPOUND X IS APPROXIMATELY 8.5.

compound Y is a strong acid , so statement 1 is wrong.

the pH at equivalence of strong acid- strong base is 7.0 and that of weak acid X and strong base is about 8.5 so statement 2 is wrong.

Both acids x and y have used the same amount of same concentration base, thus both must be of same concentration, making statement 4 wrong.

compound x has much higher pH at start inspite of same concentration as Y , so x is a weak acid , while Y is a strong acid.
