NaOH is a strong base. What will be pH of 5.0 10⁻² M NaOH solution ? ( 2=0.3)

Options

  1. A14.00
  2. B13.70
  3. C13.00
  4. D12.70

Correct answer

D. 12.70

Step-by-step solution

Given [ OH ⁻ ]=5 10⁻² aligned & pOH =- 5 10⁻² & =- 5+2 10=1.30 & pH + pOH =14 & pH =14- pOH & =14-1.30=12.70 aligned
