Question

Arrange the following solutions in the decreasing order of pOH : (A) 0.01 M HCl (B) 0.01 M NaOH (C) 0.01 M CH3COONa (D) 0.01 M NaCl (A) (B) > (C) > (D) > (A) (B) (A) > (C) > (D) > (B) (C) (B) > (D) > (C) > (A) (D) (A) > (D) > (C) > (B)

Answer: D

💡 Solution & Explanation

pH of 0.01 M HCl = 2 pH of 0.01 M NaOH = 12 pH of 0.01 M CH3COONa > 7 pH of 0.01 M NaCl = 7 So the order of pH : B > C > D > A
