6. The pOH of a solution of NaOH is 11.30. What is the [H+

] for this solution?

The [H⁺] for this soluton is 2*10⁻³ M

Explanation:

pH, short for Hydrogen Potential and pOH, or OH potential, are parameters used to measure the degree of acidity or alkalinity of substances.

The values that compose them vary from 0 to 14 and the pH value can be directly related to that of pOH by means of:

pH + pOH = 14

In this case, pOH=11.30, so

pH + 11.30 = 14

Solving:

pH = 14 - 11.30

pH = 2.7

Mathematically the pH is the negative logarithm of the molar concentration of the hydrogen or proton ions (H⁺) or hydronium ions (H₃O):

'pH = - log [H⁺] = - log [H₃O]

Being pH=2.7:

2.7 = - log [H⁺]

[H⁺] = 10⁻² ⁷

[H⁺]=1.995*10⁻³ M≅ 2*10⁻³ M

The [H⁺] for this soluton is 2*10⁻³ M
