WebThe pH level is a function of the hydrogen atom activity, as the hydrogen activity is a reasonable indicator of the water’s acidity or alkalinity. As seen below, the pH scale ranges from 0 to 14 when 7.0 is neutral. It is said that water with a low pH is acidic and that water with a high pH is basic, or alkaline. WebJan 30, 2024 · The equation to find the pH of a solution using its hydronium concentration is: pH = − log(H3O +) Using this equation, we find the pH of pure water to be 7. This is considered to be neutral on the pH scale. The pH can either go up or down depending on the change in hydronium concentration.
