The pH of 0.01 M NaOH (a q) solution will be

Options

  1. A7.01
  2. B2
  3. C12
  4. D9

Correct answer

C. 12

Step-by-step solution

NaOH is a strong base, thus aligned [ OH ⁻ ] & =0.0 M =10⁻² M pOH & =- [ OH ⁻ ]=- (10⁻² )=2 aligned We know that, pH + pOH =14 pH =14-2=12 Thus, option (3) is correct.
