Find [ OH ⁻ ] if a monoacidic base is 3 % ionised in its 0.04 M solution.
Options
- A3.1 10⁻² ~mol ~L ⁻¹
- B4.5 10⁻³ ~mol ~L ⁻¹
- C9.0 10⁻² ~mol ~L ⁻¹
- D1.2 10⁻³ ~mol ~L ⁻¹
Correct answer
D. 1.2 10⁻³ ~mol ~L ⁻¹
Step-by-step solution
For a monoacidic base, aligned & [ OH ⁻ ]= c & [ OH ⁻ ]=0.04 3 100 & [ OH ⁻ ]=1.2 10⁻³ ~mol ~L ⁻¹ aligned
