Calculate the amounts of acid and base forms of the buffer needed to prepare 2 L of a 0.1 M acetate buffer, pH 5.2.
my answer:Given that the concentration of the buffer is 2 x 0.1 = 0.2 molar
The concentration of the acid
pH = 5.2
H+ = - antilog 5.2
acid = 6.3 x 10 ^ -6 mol/dm3
ratio of salt by acid = 0.2
Concentration of the salt
0.2 = salt / 6.3 x 10 ^ -6
Salt = 0.2 x 6.3 x 10 ^-6
salt = 1.26 x 10 ^ -6 mol/dm3
