Ph and buffers defined to be able to add a strong acid or base to a solution without causing a large change in the ph, we need to create a buffer solution. Acid base balance and buffers (acid & base ph) by: harsaan nithiananthan everyday, though we do not normally recognize it, we are constantly engulfing. Two ways to make a buffer add the acid and conjugate base to the solution in a defined proportion method 1 method 2 add a strong acid to the weak base.
