What is the hydronium ion concentration of a solution with a poh of 7.20?

1.56 × 10−6 m
1.79 × 10−6 m
1.58 × 10−7 m
2.78 × 10−7 m

The concentration of hydronium ions in a solution is

Explanation:

We are given:

pOH of the solution = 7.2

To calculate the hydronium ion concentration of the solution, we need to determine the pH of the solution first. And to calculate that we use the equation:

pH is defined as negative logarithm of hydrogen ion concentration. It is basically defined as the power of hydrogen ions in a solution.

Mathematically,

pH of the solution = 6.8

Putting values in above equation, we get:

Hence, the concentration of hydronium ions in a solution is
