A saturated solution of copper (II) hydroxide is prepared in a beaker by adding the solid to water and stirring. When the solution is prepared, crystals of copper (ll) hydroxide remain on the bottom of the beaker.

Which change will cause the molar solubility of copper (II) hydroxide to increase?

A)addition of solid copper chloride

B)

addition of solid sodium hydroxide

C)

addition of aqueous hydrochloric acid

D)

dilution of the solution by addition of water

addition of aqueous hydrochloric acid

Explanation:

The solubility of copper (ll) hydroxide in water is negligible. This implies that the substance is only slightly soluble in water.

However, the addition of aqueous hydrochloric acid leads to the following reaction;

Cu(OH)2 + 2HCl > CuCl2 + 2H2O

Copper II chloride is soluble in water hence the crystals dissolve when stirred. and the molar solubility increases.

aluminum

i guess but i think im right

answer: lol

explanation:
