Classify the following buffers into different types :a. CH3COOH + CH3C

1.	Classify the following buffers into different types :a. CH3COOH + CH3COONab. NH4OH + NH4Clc. Sodium benzoate + benzoic acidd. Cu(OH)2 + CuCl2
Answer» (a) Acidic buffer (CH₃COOH + CH₃COONa) (b) Basic buffer (NH₄OH + NH₄Cl) (c) Acidic buffer (Sodium benzoate + benzoic acid) (d) Basic buffer (Cu(OH)₂ + CuCl₂) [Note : Cu(OH)₂ being insoluble is not used to prepare a buffer solution.]
