Explanation:
pOH is defined as the negative logarithm of hydroxide ion concentration present in the solution.
We are given:
Concentration of (Conversion factor: )
1 mole of calcium hydroxide produces 1 mole of calcium ions and 2 moles of hydroxide ions
Concentration of
Putting values in above equation, we get:
We know:
Hence, the pH of the solution is 13.
