WebWhen the H+ ion is added to the solution, the base that is present will react with the H+ ion to neutralize it. So the added H+ reacts with A- to form HA. So for the particulate diagrams, this added H+ is going to react with one of the A minuses present in the buffer solution. So the H+ and the A- form an HA. WebThe resulting solution will resist major changes in pH when an acid or base is added to buffer solutions. buffer solutions. Consider what would happen in a solution containing both formic acid and sodium formate when acid or base are added. Adding acid (a source of H 3 O +) stresses the system by adding a product.
