Question

A 50 ml sample of a 1.0 M solution of CuSO4 is mixed with 50 mL of 2.0 M KOH in a calorimeter. The temperature of both solutions was 23.9°C before mixing and 33.5°C ofter mixing. The heat capacity of the calorimeter is 12.1 J/K. From these data, calculate AH for the process: CuSO4 (1M) + 2KOH (2M) - Cu(OH)2 (8) + K2504 (0.5M) Assume that the specific heat and density of the solution after mixing are the same as those of pure water and that the volumes are additive.

Answer 1

$\large \Delta$H for the process = -4132.8 J
