The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH = − log [H+] where [H+] is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 4.92 × 10-³ mol/L, the pH is b. If the pH of a solution is 3.078, the hydrogen ion concentration is mol/L.

Question
The pH scale was designed to make it
convenient to express hydrogen ion
concentrations that are small in aqueous
solutions. The definiton of pH is in terms of
base 10 logarithms.
pH = − log [H+]
where [+] is the hydrogen ion
concentration.
a. If the hydrogen ion concentration
in a solution is 4.92 × 10-³
mol/L, the pH is
b. If the pH of a solution is 3.078, the
hydrogen ion concentration is
mol/L.
