How is the $pH$ of a solution of an acid influenced when it is diluted?
(N/A) When an acid is diluted,the concentration of hydrogen ions $(H^+)$ per unit volume decreases.
Since $pH$ is defined as the negative logarithm of the hydrogen ion concentration $(pH = -\log[H^+])$,a decrease in the concentration of $H^+$ ions leads to an increase in the $pH$ value of the solution.
