# Problem: Consider two solutions, the first being 50.0 mL of 1.00 M CuSO4 and the second 50.0 mL of 2.00 M KOH. When the two solutions are mixed in a constant-pressure calorimeter, a precipitate forms and the temperature of the mixture rises from 21.5 oC to 27.7 oC.Write net ionic equation for the reaction that occurs when the two solutions are mixed.

###### FREE Expert Solution

We are asked to write net ionic equation for the reaction that occurs when the two solutions are mixed.

CuSO4 (aq) + 2 KOH (aq) → Cu(OH)2 (s) + K2SO4 (aq)

Dissociate the aqueous species to ions:

Cu2+(aq) + SO42-(aq) + 2 K+(aq)  + 2 OH-(aq) →Cu(OH)2 (s)  + 2 K+(aq)  + SO42-(aq)
