The molar concentration of an aqueous `CH_3COONa` solution is 0.01(M). Calculate
degree of hydrolysis

Text Solution

Verified by Experts

`CH_3COONa` is the salt of weak acid `(CH_3COOH)` and strong base (NaOH) . In the aqueous solution of such salts, hydrolysis constant `h=sqrt((k_w)/(K_axxc))` hydrolysis constant
`K_h=(K_w)/(K_a)` and pH of the solution`=7+1/2pK_a+1/2logc`
`h=sqrt((k_w)/(k_axxc))=sqrt((10^(-14))/(1.8xx10^(-5)xx0.1))=2.35xx10^(-4)`
