Buffer Solutions | MCQs

Explanation

The pH of a mixture of CH₃COONa (sodium acetate) and CH₃COOH (acetic acid) is C. <7. 

This mixture forms a buffer solution, where the weak acid (CH₃COOH)

Its conjugate base (CH₃COO-) is present together, resulting in a pH that is less than 7 (acidic) but not extremely so
