The heats of neutralisation of $CH_{3} COOH$ , $HCOOH, HCN$ and $H_{2} S$ are -13.2,-13.4,-2.9 and $- 3.8 kCal$ per equivalent respectively. Arrange the acids in increasing order of acidic strength.

Options:

Answer:

Solution:

The greater the (negative value) of heat of neutralisation, the more is the strength of the acid. Hence, $HCOOH > CH_{3} COOH > H_{2} S > HCN$
