Question

The pH of ${10}^{-8}$ molar solution of $HCl$ in water is:

• A. $8$
• B. $-8$
• C. between $7$ and $8$
• D. between $6$ and $7$

Answer 1

The correct option is D between $6$ and $7$

As the solution is acidic , $pH<7$, This is because $\left[H^{+}\right]$ from $H_{2}O\left[{10}^{-7}\right]$ cannot be neglected in comparison to ${10}^{-8}$
Option D is correct.
