Solid calcium hydroxide is dissolved in water until the pH of the solution is 10.44. Determine the concentration of the calcium hydroxide in the solution.

1.38x10⁻⁴ M

Explanation:

First, we calculate the pOH of the solution, using the given pH:

pOH = 14 - pHpOH = 14 - 10.44pOH = 3.56

Now we calculate the concentration of OH⁻, using the pOH:

pOH = -log[OH⁻][OH⁻] = = 2.75x10⁻⁴ M

Following the reaction Ca(OH)₂ → Ca⁺² + 2OH⁻, we divide [OH⁻] by 2 to calculate [Ca(OH)₂]:

[Ca(OH)₂] = 2.75x10⁻⁴ M / 2 [Ca(OH)₂] = 1.38x10⁻⁴ M

What do you mean by that? like the contents? the thc level?
