determine mass of sodium acetate and volumes of 3M HCN solution required for preparing a 250ml buffer solution of pH = 5.3 with salt concentration 0.5M.  Ka = 2*10-5.

Dear student,

An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt.

A common example would be a mixture of ethanoic acid and sodium ethanoate in solution. In this case, if the solution contained equal molar concentrations of both the acid and the salt, it would have a pH of 4.76. It wouldn't matter what the concentrations were, as long as they were the same.
