MHT CET2009ChemistryIonic Equilibrium
In a solution, 0.02 M acetic acid is 4 % dissociated. The [ OH ⁻ ] in the solution is
Options
- A8 10⁻⁴
- B2 10⁻¹⁴
- C8 10¹⁰
- D1.25 10⁻¹¹
Correct answer
D. 1.25 10⁻¹¹
Step-by-step solution
[ H ⁺ ]= ² C² = (0.02)² (0.04)² =8 10⁻⁴ [ H ⁺ ] [ OH ⁻ ]=10⁻¹⁴ [ OH ⁻ ]= 10⁻¹⁴ 8 10⁻⁴ =1.25 10⁻¹¹ M
