The pH of a 0.001 M solution of HCl is

Options

  1. A0
  2. B3
  3. C5
  4. D10

Correct answer

B. 3

Step-by-step solution

[H+]=0.001pH=−log⁡[H+]=−log⁡[10−3]=3\begin{aligned} {\left[\mathrm{H}^{+}\right] } & =0.001 \\ \mathrm{pH} & =-\log \left[\mathrm{H}^{+}\right] \\ & =-\log \left[10^{-3}\right] \\ & =3 \end{aligned})$
