What is the hydrogen ion concentration in a solution with a pH of 8?

The pH of a solution is a measure of its acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral. A pH less than 7 indicates an acidic solution, while a pH greater than 7 indicates a basic or alkaline solution.

The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen ion concentration, [H+]. Mathematically, this is expressed as:

pH = -log[H+]

To find the hydrogen ion concentration of a solution with a pH of 8, you would rearrange the formula to solve for [H+]:

[H+] = 10^-pH

Substitute 8 for pH:

[H+] = 10^-8

So, the hydrogen ion concentration in a solution with a pH of 8 is 1 x 10^-8 M.
