What is the pH of `0.01 M ` solution of `CH _(3) COONa` in water at 298 K

Text Solution

Verified by Experts

`pK _(w) =- log K _(w) = - log 1 008 xx 10 ^(14) = 13. 997 = 14`
`pK _(a) =- log K _(a) =- log 1. 75 xx 10 ^(-5) = 4. 76, log x = log (10 ^(-2)) = - 2`
`pH = 14. 0 - 1//2 pK _(w) + 1//2 log x + 1//2 PK _(a) = 14 - 1//2 (14.0) + 1//2 (-2) + 1//2 (4.76 = 8.38)`
