Question

What is the value of pH for a neutral solution?

Answer 1

pH

• The pH of the solution is given by,

$\mathrm{pH}=-\log \left[{\mathrm{H}}^{+}\right]$,

Neutral Solution

• In a neutral solution the $\left[{\mathrm{H}}^{+}\right]={10}^{-7}$
• Hence, the pH of a neutral solution

$$\begin{gathered} \mathrm{pH}=\log {10}^{-7} \\ =7 \end{gathered}$$
