A liquid has a pH of 5.62. Find the hydrogen ion concentration.

The pH value of a solution is defined as the negative logarithm (base 10) of the hydrogen ion concentration ([H+]) in moles per liter (M).

Mathematically, pH = -log[H+]

Rearranging the equation, we find [H+] = 10^(-pH)

Therefore, [H+] = 10^(-5.62)

Using a calculator, we find that the hydrogen ion concentration of the liquid is approximately 2.31 x 10^(-6) M.
