Question

Give Two Examples For Acidic Buffer.

Answer 1

Acidic Buffer:

• Buffer is a solution that retains the change in its pH to any great extent, upon the addition of a small amount of acid, base, or water to the solution.
• Acidic Buffer is one type of buffer solution which is acidic in nature.
• An acidic buffer solution is prepared by mixing any weak acid along with its corresponding salt with a strong base.
• Examples of acidic buffer:

Acetic acid + Sodium acetate (${\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{CH}}_3\mathrm{COONa},$) Benzoic acid + Sodium benzoate(${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COOH}+{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COONa}$) etc.

Hence, two examples for acidic buffer are : acetic acid + sodium acetate (${\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{CH}}_3\mathrm{COONa},$) benzoic acid + sodium benzoate(${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COOH}+{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COONa}$).
