These buffer solutions are used to maintain basic conditions. Basic buffer has a basic pH and is prepared by mixing a weak base and its salt of the strong acid. Consider base buffer solution, containing a weak base and salt with a strong acid, So pH and pOH can be given by the equation:pOH of a basic buffer = pK\\[_{b}\\] +  log (salt/acid)Or, pH of a basic buffer = pK\\[_{a}\\] – log (salt/acid)
