Consider the reaction below:Cu(OH)2(s) ⇌ Cu2+(aq) + 2OH─(aq)0.050 g of solid copper(II) hydroxide is added to 2.00 dm3 of water in a glass container and the mixture is allowed to reach equilibrium. If thereafter the equilibrium mixture is made alkaline by adding 250 cm3 of a 0.100 mol.dm─3 solution of ammonia, then:A. less solid copper(II) hydroxide will be left in the containerB. more solid copper(II) hydroxide will precipitateC. the solubility of solid copper(II) hydroxide will reduceD. less solid copper(II) hydroxide will dissolve than beforeE. the concentration of free copper(II) ions will increase
