Calculate for `0.01N` solution of sodium acetate,
a. Hydrolysis constant b. Dergee of hydrolysis
c. `pH` Given `K_(a) = 1.9 xx 10^(-5)`

Explanation

For
`{:(,CH_(3)COONa+,H_(2)OhArr,CH_(3)COOH+,NaOH),("Before1hysrolysis",1,,0,0),("After hydrolysis",1-h,,h,h):}`
a. `:. K_(h) = (K_(w))/(K_(a)) = (10^(-14))/(1.9xx10^(-5)) = 5.26 xx 10^(-10)`
b. `h = sqrt((K_(h))/(c)) = sqrt((5.26xx10^(-10))/(0.01)) = 2.29 xx 10^(-4)`
c. `[overset(Θ)OH]` from `NaOH`, a strong alkali `= Ch`
`:. =0.01 xx 2.29 xx 10^(-4) = 2.29 xx 10^(-6)M`
`:. pOH = 5.64` and `pH = 8.36`
