What is the hydronium concentration of a solution at pH 7?

Question

Quizplus · Accepted Answer

The pH scale is a measure of the hydrogen ion concentration in a solution. The pH of a solution is calculated as the negative logarithm (base 10) of the hydrogen ion concentration. At pH 7, the hydrogen ion concentration (or hydronium ion concentration, H3O+) is 1 x 10^-7 M, which is a neutral pH value, representing a balance between hydrogen ions and hydroxide ions in pure water.
