The pH= 7.57 ,  pOH = 6.86, and  [OH-] = 1.58 x 10⁻⁴ M M of the given solution.

What is pH?

pH is a scale that measures the acidity and basicity of a solution. Its ranges from 1 to 14. Seven is neutral.

The H given is 7. 2 × 10⁻⁸ m

Calculating the pOH

[H⁺] = 10^(-7.20)

[H⁺] = 6.31 x 10⁻⁹ M

pOH = 14 - 7.2

pOH = 6.8

Calculating the [oh−]

[OH⁻] = 1 x 10⁻¹⁴ / 6.31 x 10⁻⁹

[OH⁻] = 1.58 x 10⁻⁴ M

Calculating the pH

pH = 14 - 6.43

pH = 7.57

Thus, the pH= 7.57 , pOH = 6.86, and  [OH-] = 1.58 x 10⁻⁴ M.
