BRAINCAKEDetermining the Enthalpy Change of a Reaction
When carrying out the enthalpy change of a reaction between two aqueous solutions, the immediate surrounding is the solution itself, so a thermometer can be placed in the solution to record the temperature change. To correct for heat loss a cooling curve can be used.
