Question

Which one of the following is correct option: hydrogen,

hydroxide, peroxide?
pH is a measure of the
ion concentration of a
solution.

Answer 1

hydrogen

Step-by-step explanation:

pH is a measure of the ion concentration of hydrogen in a solution.

In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.

Mathematically, the pH of a solution is given by
`pH = -log 10[H^(+)]`

Hence, a solution with a pH of 7 is neutral.

Also, a solution with a pH below 7 is acidic but basic if it's pH is above 7.
