• A. pH
• B. pOH
• C. $\left[H^{+}\right]$
• D. None of these

Answer 1

The correct option is A pH

The negative logarithm of the hydrogen ion concentration of a medium or a solution is known as the $pH$ of the medium. It is expressed as-
$pH=$$-log\left[H^{+}\right]$, where $\left[H^{+}\right]$ is the concentration of the hydrogen ion in the solution.
