FREE Expert Solution

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)2strong base


We’re going to calculate the pH of the solution using the following steps:
