Question

When strong base (NaOH) is added to the weak acid (acetic acid, $C{H}_{3}COOH)$ , then dissociation of acetic acid increases; this effect is known as

• A. common ion effect
• B. reverse ion effect
• C. saltation effect
• D. solubility effect

Answer 1

Answer: (B)

${\text{CH}}_{\text{3}}\text{COOH}\text{+}\text{NaOH}\rightleftharpoons {\text{CH}}_{\text{3}}\text{COONa}\text{+}{\text{H}}_{\text{2}}\text{O}$

Ionisation of acetic acid will increase with the progress of its neutralization. This effect is called reverse ion effect.
