The equilibrium that exists in aqueous solution, CH 3 COOH ⇌ CH 3 COO − + H + if dil HCl is added at constant temperature, then

Options

  1. AThe equilibrium constant will increase
  2. BThe equilibrium constant will decrease
  3. CConcentration of C H 3 C O O - will decrease
  4. DConcentration of C H 3 C O O - will increase

Correct answer

C. Concentration of C H 3 C O O - will decrease

Step-by-step solution

Due to common ion effect of H + , the ionisation of C H 3 COOH is suppress hence the concentration of C H 3 C O O - will decrease.
