Answer #1

ANSWER :

(B) HF titrated by KOH .

Reason - the curve is increasing initially which is a case of strong base and weak acid and then it has an almost flat slope and then the graph rise at pH about 6 .
Reason - KOH is taken as titratant as after titration the pH is basic and if all the acid gets neutralised then the pH indicates the titrant added is basic in nature .
In case only HF is weak acid and KOH is strong base and the titrant is KOH hence HF is being titrated by KOH.
