Calcium hydroxide and lead chloride have very limited solubility in neutral water (?? ≈ 7.0). However, when acid is added to the reactor, the solubility of calcium hydroxide increases significantly, however, the solubility of lead chloride does not change. Which of the following statements explains the impact of acid?

Question

Calcium hydroxide and lead chloride have very limited solubility in neutral water (?? ≈ 7.0). However, when acid is added to the reactor, the solubility of calcium hydroxide increases significantly, however, the solubility of lead chloride does not change. Which of the following statements explains the impact of acid?

Image below

A. The acid reacts with the calcium ions that are generated.
B. Acid increases the solubility of any slightly soluble solid.
C. The acid reacts with the hydroxide that is produced from the solubilization of calcium hydroxide. By consuming the hydroxyl ions, this has a Le Chatelier type impact and results in more calcium hydroxide being dissolved to produce more calcium ions.

Justify all the alternatives.
