We’re being asked to calculate the pH of a saturated solution of calcium hydroxide containing 0.38 grams of calcium hydroxide in 250 mL of solution.
Let’s first determine what type of base is calcium hydroxide:
• Any Group 2A metal (from Ca2+ to Ba2+) when combined with OH-, H-, O2- or NH2- makes a strong base
• Ca (Group 2A metal) is paired with OH-
• Ca(OH)2 → strong base
We’re going to calculate the pH of the solution using the following steps:
A saturated solution of calcium hydroxide contains 0.38 grams of calcium hydroxide in each 250 mL of solution. What is the pH of saturated calcium hydroxide?
