What’s the PH and OH- of 6.0 x 10^-10?

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

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      

the answer is a and have a great day
