Consider two solutions, the first being 50.0 mL of 1.00 MCuSO4 and the second 50.0 mL of 2.00 MKOH. When the two solutions are mixed in a constant-pressure calorimeter, a precipitate forms and the temperature of the mixture rises from 21.5 °C to 27.7 °C.
(a) Before mixing, how many grams of Cu are present in the solution of CuSO4?
(b) Predict the identity of the precipitate in the reaction.
(c) Write complete and net ionic equations for the reaction that occurs when the two solutions are mixed.
(d) From the calorimetric data, calculate ΔH for the reaction that occurs on mixing. Assume that the calorimeter absorbs only a negligible quantity of heat, that the total volume of the solution is 100.0 mL, and that the specific heat and density of the solution after mixing are the same as that of pure water.
