A buffer solution is prepared by adding 0.20 mole of ammonia and 0.30 mole of ammonium chloride to enough water to make one liter of solution. Ka = 5.7 x 10-10 for ammonium.

Calculate:

a. The [H+] and the pH of the buffer

b. The [H+] and the pH of the buffer after t he addition of 0.020 mole of HCl

c. The [H+] and the pH of the buffer after t he addition of 0.020 mole of NaOH
