Answer:

The answer to your question is pH = 9.2; [OH] = 1.58 x 10⁻⁵

Step-by-step explanation:

Data

[H⁺] = 6.0 x 10⁻¹⁰ M

pH = ?

pH definition. pH measures the hydrogen concentration. pH measures the acidity and the alkalinity of a solution. A solution is acid if the pH goes from 0 to 6.9, a neutral solution has a pH of 7 and an alkali solution has a pH from 7.1 to 14.

pOH measures the [OH⁻] concentration

Formula

pH = -log[H⁺]

pH + pOH = 14

-Substitution

pH = -log[6 x 10⁻¹⁰]

-Simplification

pH = - (-9.2)

pH = 9.2

-Calculate pOH

pOH = 14 - pH

pOH = 14 - 9.2

pOH = 4.8

-Calculate the concentration of OH⁻

pOH = -log[OH⁻]

[OH⁻] = -antilog4.8

[OH] = 1.58 x 10⁻⁵
