Question
The pH of a solution is a measure of the molar concentration of hydrogen ions, HO in moles per liter, in the
solution, which means that it is a measure of the acidity or basicity of the solution. The letters pH stand for
"power of hydrogen," and the numerical value is defined as pH =- log o[H]
10
Very acidic corresponds to pH values near 1, neutral corresponds to a pH near 7 (pure water), and very basic
corresponds to values near 14.
