If you place an aqueous solutions of CuBr2 (which is then Cu(H2O)4 2+) with solid KBr added to it in a hot water bath what do you observe and why?

These are ordinary compounds available in most labs. Why not try it and see what happens? That's chemistry.

DrBob's suggestion is very good. If you do not have easy access to a lab, here is a clue:
• Cu(H2O)4^2+ ions dominate at low CuBr2 concentrations and they are blue.
• CuBr4^2- ion concentrations appear at high Br- ion concentrations and their color is green.
• Cu(H2O)4^2+ ions dominate at low CuBr2 concentrations and they are blue.
• CuBr4^2- ion concentrations appear at high Br- ion concentrations and their color is green.

As a follow up to GK's response, think in terms of Le Chatelier's Principle.
