The estimation of the acidic and the basic character of a solution is called and defined by the pH. The [tex]\rm [H^{+}][/tex] concentration of the solution will be [tex]\rm 1.77\times 10^{-4}.[/tex]
pH is a measurement of the free hydrogen and hydroxyl ions in the solution of the substance.
It can be calculated as:
[tex]\rm pH = - \rm log[H^{+}][/tex]
Given,
pH = 3.75
Substituting values in the equation:
[tex]\begin{aligned}\rm 3.75 &= -\rm log[H^{+}]\\\\\rm [H^{+}] &= 10^{-3.75}\\\\&= 1.7782 \times 10^{-4}\end{aligned}[/tex]
Therefore, [tex]\rm 1.77\times 10^{-4}[/tex] is the concentration of the hydrogen ions.
