How to Calculate pH Worked Chemistry Problem

pH is a measure of the acidity or alkalinity of a chemical solution. A solution with a pH less than 7 is considered to be acidic. One with a pH greater than 7 is alkaline. A pH equal to 7 is a neutral solution. Here is a simple example of how to calculate the pH of a solution when the hydrogen ion concentration is known: Question What is the pH of a solution with [H] 1 x 10-6 M. Solution pH is calculated by the formula pH - log [H] Substitute [H] with the concentration in the question. pH - log (1 x 10-6)pH -(-6)pH 6 Answer The pH of the solution is 6.
