Answer to Question #94867 in Biochemistry for Damaris Martinez

Question

What does pH measure?


the total number of base molecules in solution

the concentration of hydrogen ions in solution

the total number of acid molecules in solution

the concentration of oxygen atoms in soluti

Answer 1

Answer. The concentration of hydrogen ions in solution 

The formula for pH is  pH = -log[H+]. This means pH is the negative base 10 logarithm of the hydrogen ion concentration of a solution.

The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
