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 c = log(10^(-2)) = -2`
`pH = 14.0 - (1)/(2)pK_(w) + (1)/(2)log c + (1)/(2)pK_(a) = 14 - (1)/(2)(14.0) + (1)/(2)(-2) + (1)/(2)(4.76) = 8.38`
