A) \[\operatorname{N}{{H}_{4}}Cl\,\,+\,\,N{{H}_{4}}OH\]
B) \[{{\operatorname{CH}}_{3}}COOH\,\,+\,\,C{{H}_{3}}COONa\]
C) 40 ml of 0.1 M NaCN + 20 mL of 0.1 M HCN
D) All of the above
Correct Answer: D
Solution :
Buffer is a solution of weak acid and a conjugate of weak acid or a weak base and a conjugate of weak base \[N{{H}_{4}}Cl+N{{H}_{4}}OH\] \[C{{H}_{3}}COOH+ C{{H}_{3}}COONa, \,NaCN+HCN\] +2+ 4-2 + 2-2 . +4You need to login to perform this action.
