Question

The pKa of acetic acid and pKb of ammonium hydroxide are 4.76 and 4.75 respectively. Calculate the pH of the ammonium acetate solution? ​

Answer 1

Answer:

weak acid weak Base salt

pH = 7 + 1/2Pka -1/2 pKb

pH = 7.005

pH = approx (7)

• ❤..${pH}$=$+{1/2[pka - pkb]}$
• =${7+1/2[4.76-4.75]}$
• =${7+1/2[0.01]=7+0.005=7.005}$
