Consider an acetate buffer system made up of acetic acid and sodium acetate, initially at the same pH as its pka (4.76). When small amount of base is added to this buffer which of the following reactions is most likely to occur which will prevent increase in pH of the buffer? O a. CH3COOH + N2OH - CH3C00+ H20 Ob. None of the above OC CH3CO0" + HCI CH3COOH + Cr Od CHạCO0 + NAOH - CH3COOH + Na* Oe. CH3COOH + HCI - CH3CO0 + H20
