Question

Which of the following effect increases the solubility of Ca(OH)2?

O Adding an acidic solution
O Adding KOH
O Adding solid CaCl,
O Adding solid NaOH
O Adding CaCO3

Answer 1

adding an acidic solution

Step-by-step explanation:

Strong acids dissociate completely in water and the H⁺ ions react with the OH⁻ ions to make H₂O. If we add an acid to our solution of Ca(OH)₂, the acid protons would react with some of the OH⁻ ions and drive the equilibrium to the right. More of the solid Ca(OH)₂ should dissolve.
