Question

If the pK a of acetic acid and pK b of NH 4 OH are 4.76 and 4.75 respectively, what will be the pH of ammonium acetate solution?, 9.51, 7.005, 7.00, 6.9

When a weak acid (acetic acid) and weak base NH 4 OH are mixed to form a solution. pH of the solution is then determined by following formula: pH = 7 + 1 2 pK a − pK b Given, pK a = 4 .76, pK b = 4 .75 pH = 7 + 1 2 4 .76 − 4 .75 pH = 7 + 0 .005 pH = 7 .005
