    Which of the following pairs constitutes a buffer?

    Which of the following pairs will not form a buffer solution?

    The solution which consumes [H^(+)] or [OH^(-)] or both simultaneously from externally added base in order to give negligible change in pH , is known as buffer solution. In general, the solution resists the change in pH. Buffer solution does not mean that there does not occur a pH change in pH. Buffer solution des not mean that there does not occur a pH change at all. It implies the pH change occurs but in neglibible amount. There are two types of buffer (i) Acidic buffer: it is a mixture of weak acid and its salt acid strong base. (ii) Basic buffer : It is a mixture of weak base and its salt with strong acid. Which of the following mixture will be a buffer solution when dissolved in 500 mL of water:
