The pKa of acetic acid and pKb, ofammonium hydroxide are 4.76 and 4.75respectively. Calculate the pH ofammonium acetate solution. |
Answer» <p>when a weak acid and a weak baseare mixed to form a solution,the ph of the solution is determined by following formula</p><p>ph=7+1/2[pka-pkb]</p><p> =7+1/2[4.76-4.75]</p><p> =7+1/2[0.01]</p><p> =7+0.005</p><p>ph=7.005</p> | |
