Q. When copper(II) sulfate, CuSO4, dissolves in water, both of the resulting ions can become hydrated. (a) Write a balanced chemical equation that shows copper(II) sulfate dissolving in water and the hydration of Cu24- with 4 water molecules and S042- with 14 water molecules. (Complex ions take the general form: Ag(NH3)2+. Omit states-of-matter from your answer.) (b) Draw a 2-dimensional diagram that illustrates how the 4 molecules of water arrange themselves around the copper(II) ion.
