The `pH` of a solution at `25^(@)C` containing `0.10 m` sodium acetate and `0.03 m` acetic acid is (`pK_(a)` for `CH_(3)COOH=4.57`)

The pH of a solution at 25°C containing 0.20 M sodium acetate and 0.06 M acetic acid is (pK_a for CH_3COOH = 4.74 and log 3 = 0.477)

The pH of a buffer solution containing 0.1M acetic acid and 0.1 M sodium acetate (pKa of a acetic acid is 4.74) is

One litre of buffer solution contains 0.1 mole of acetic acid add 1 mole of sodium acetate. Find its pH if pK_(a) of CH_(3)COOH is 4.8.

pH of 0.005 M calcium acetate (pK_a" of " CH_3COOH= 4.74) is

Calculate pH of 0.05 M Acetic acid solution , if K_(a)(CH_(3)COOH) = 1.74 xx 10^(-5) .
