3. Copper hydroxide dissolves in water according to the following equation. It is only very slightly soluble. Cu(OH)2(s) Cu2 (aq) 2OH- (aq) a. Explain how the solubility can be increased by adding HCl to the solution. b. Explain how the concentration of copper (II) ion or of hydroxide ion can be reduced in the solution so that more of the solid copper hydroxide can be dissolved.
