WebA buffer is a solution whose function is to minimize the change in pH when a base or an acid is added to the solution ; Most buffers consist of a weak acid (which releases H + ions) and a weak base (which binds H + ions) If an acidic solution is added to a buffer solution, the buffer will combine with the extra H + ions and help to maintain the pH
