$K _{ u }$ values for acids $H _{2} SO _{3}, HNO _{2}, CH _{3} COOH$ and $HCN$ are respectively $1.3 imes 10^{-2}, 4 imes 10^{-4}, 1.8 imes 10^{-5}$ and $4 imes 10^{-10}$ , which of the above acids produces stronger conjugate base in aqueous solution?

Question

$K _{ u }$ values for acids $H _{2} SO _{3}, HNO _{2}, CH _{3} COOH$ and $HCN$ are respectively $1.3 	imes 10^{-2}, 4 	imes 10^{-4}, 1.8 	imes 10^{-5}$ and $4 	imes 10^{-10}$ , which of the above acids produces stronger conjugate base in aqueous solution?

Collegedunia Admin · Accepted Answer

$K _{ a }( HCN )=4 	imes 10^{-10} $ $HCN ightleftharpoons H ^{+}+ CN ^{-}$ Weaker the acid, stronger the conjugate base.
