Addition of CH3COONa in water gives
Correct answer: C. Basic solution
- A. Standard solution
- B. Buffer solution
- C. Basic solution
- D. Acidic solution
Explanation
When CH3COONa (sodium acetate) dissolves in water, it dissociates into CH3COO- and Na+. The acetate ion (CH3COO-) undergoes hydrolysis with water, forming acetic acid (CH3COOH) and hydroxide ions (OH-), thus increasing the concentration of OH- and making the solution basic. Therefore, the correct answer is 'Basic solution.' The other options are incorrect: 'Standard solution' and 'Buffer solution' do not describe the nature of the solution formed, and 'Acidic solution' is incorrect because the formation of OH- results in a basic solution.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
