Vedclass · Answer

(A) Electrical conductivity of an aqueous solution depends on the concentration of ions produced.Greater the acidic strength (higher $K_a$ value),greater will be the degree of dissociation and hence higher electrical conductivity.The $K_a$ values at $298 \ K$ are:Formic acid $(HCOOH)$: $1.8 	imes 10^{-4}$Benzoic acid $(C_6H_5COOH)$: $6.5 	imes 10^{-5}$Acetic acid $(CH_3COOH)$: $1.8 	imes 10^{-5}$Since the order of acidic strength is Formic acid > Benzoic acid > Acetic acid,the order of electrical conductivity is $a > c > b$.

The decreasing order of electrical conductivity of the following aqueous solutions is:
$0.1 \ M$ Formic acid $(a)$
$0.1 \ M$ Acetic acid $(b)$
$0.1 \ M$ Benzoic acid $(c)$
