Enter either value then hit calculate to determine either the hydrogen ion concentration or the pH.

Ph To Hydrogen Ion Concentration Formula

The following formula is used to calculate the hydrogen ion concentration from pH. 

[H+] = 10^-pH

Variables:

  • [H+] is the hydrogen ion concentration (moles per liter)
  • pH is the measure of acidity or alkalinity of a solution

To calculate the hydrogen ion concentration, raise 10 to the power of the negative value of the pH.

What is a Ph To Hydrogen Ion Concentration?

pH is a measure of the hydrogen ion concentration in a solution. It is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. The pH scale ranges from 0 to 14, with 7 being neutral. A pH less than 7 indicates an acidic solution, while a pH greater than 7 indicates a basic or alkaline solution. The lower the pH, the higher the concentration of hydrogen ions in the solution, and vice versa.

How to Calculate Ph To Hydrogen Ion Concentration?

The following steps outline how to calculate the hydrogen ion concentration using the pH value.

  1. First, determine the pH value.
  2. Next, use the formula [H+] = 10^-pH to calculate the hydrogen ion concentration.
  3. Finally, calculate the hydrogen ion concentration.
  4. After inserting the pH value into the formula and calculating the result, check your answer with a pH to [H+] calculator.
