Explain nh4cl to enough h2o to make one liter of solution

Reference no: EM13503686

A buffer solution is prepared by adding 0.20 mole of NH3 and 0.30 mole of NH4Cl to enough H2O to make one liter of solution.

K(a) = 5.7 x 10^-10 for NH4+

Calculate:

a-the [H+] and pH of the buffer

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

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