Consider the following solutions of equal concentrations {:(A= NH_(4)Cl,,B = CH_(3)COONa),(C = NH_(4)OH,,D = CH_(3)COOH):} A buffer solution can be obtained by mixing equal volumes of

Answer»

C and D
A and B
A and C
C and D

Solution :Buffer solution can be OBTAINED :
(i) By mixing a weak acid with its salt of a strong base.
e.g. `CH_(3)COOH + CH_(3)COONA`
(ii) By mixing a weak base with itssaltof a strong acid.
e.g. `NH_(4)OH + NH_(4)Cl`.
