When marco is sick, he tests the ph of his saliva and finds that it is 5.9. what is the hydrogen ion concentration of his saliva? (round your answer to seven decimal places.)?

Respuesta :

pH=-lg[H⁺]

[H⁺]=10⁻⁵·⁹

[H⁺]=1.259·10⁻⁶ mol/L

The saliva of Marco with a pH of 5.9 has a hydrogen ion concentration of 1.3 × 10⁻⁶ M.

When Marco is sick, the pH of his saliva is 5.9. The pH scale is used to know the acidity or basicity of a solution.

  • If pH < 7, the solution is acid.
  • If pH = 7, the solution is neutral.
  • If pH > 7, the solution is basic.

In this case, the saliva of Marco is acid. We can calculate the concentration of H⁺ using the definition of pH.

[tex]pH = -log [H^{+} ]\\[H^{+} ] = antilog -pH = antilog-5.9 = 1.3 \times 10^{-6} M[/tex]

The saliva of Marco with a pH of 5.9 has a hydrogen ion concentration of 1.3 × 10⁻⁶ M.
