I(salt) II Type of Hydrolysis
A) ${CuSO}_{4}$ I) Cationic and anionic hydrolysis
B) ${KNO}_{3}$ II) Anionic hydrolysis
C) $NaCN$ III) Cationic hydrolysis
D) ${HCOONH}_{4}$ IV) No hydrolysis
Correct match is

Moderate

Solution

${CuSO}_{4}$ … Salt of SA – WB …. ${Cu}^{+ 2}$ undergoes hydrolysis
${KNO}_{3}$ ….Salt of SA–SB … No hydrolysis
$NaCN$ …..Salt of WA – SB … ${CN}^{-}$ undergoes hydrolysis
${HCOONH}_{4}$ …Salt of WA – WB … ${HCOO}^{-}^{} & {NH}_{4}^{+}$ undergo hydrolysis.
