The pH of 10-2 M aqueous solution of sodium hydroxide is:
Correct answer: C. 12
- A. 14
- B. 10
- C. 12
- D. 13
Explanation
A 10β»Β² M NaOH solution has [ππ»β]=10 β2 So, pOH = 2, and pH = 14 β 2 = 12. Thus, the solution is strongly basic.

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.
