Question

What is the concentration (M) of a solution with a pH of 9.52 ?

Answer 1

[H⁺] = 3.02 x 10⁻¹⁰M

Step-by-step explanation:

Given parameters:

pH of the solution = 9.52

Unknown:

Concentration of the solution

Solution

There is a relationship between the pH and concentration of a solution.

pH = -log₁₀[H⁺]

The unknown here is [H⁺],

Now making it the subject of the formula

[H⁺] = Inverse log₁₀(-pH)

[H⁺] = Inverse log₁₀(-9.52)

[H⁺] = 3.02 x 10⁻¹⁰M
