How is the Hydrogen ion concentration of stomach acid – with a pH of 2.0 – found?

The definition of pH is used, which is, pH=-logH+concentration.

Since you know the pH, this turns into an algebra problem:

2.0 = -logH+concentration

Then, logH+concentration = -2

H+concentration = 10-2, or เว็บพนันออนไลน์ 1/100. The H+ concentration is 0.01 M.
