The question: The pH of a solution is defined as pH = -log[H3O+].

WebbThe pH of a solution is a measure of the concentration of hydrogen ions in a solution (or the number of hydronium ions). The number of hydrogen ions is a direct measure of how acidic or how basic a solution is. The pH scale is logarithmic and ranges from 0 to 14 ( Figure 2 ). We define pH=7.0 as neutral.
