What will be the pH of a solution of NaOH with a concentration of 10-3 M?
Correct answer: C. 11
- A. 3
- B. 14
- C. 11
- D. 7
Explanation
pOH of NaOH will be => pOH=- log[OH-]=-log[10-3]= 3 pH + pOH = 14 pH+3=14 pH= 11 As it is numerical, it can have only one possible answer.

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.
