pH of 2•4

The pH of 2•4 is not possible to determine with the given information. In order to calculate pH, the concentration of hydrogen ions (H+) must be known. Please provide more information.

To find the pH of a solution, you need to know the concentration of hydrogen ions (H+). The pH scale ranges from 0 to 14, where pH values less than 7 are acidic, pH values greater than 7 are basic, and pH 7 is neutral.

Given the concentration of a solution, we need more information to calculate the pH. The molarity (M) or activity (aH+) of hydrogen ions is required to calculate the pH.

If you provide the molarity or activity of hydrogen ions in the solution, I can help you calculate the pH.
