Enthalpy of solution of salts

LC3.3.1.3

To carry out all experiments from this subject area, we offer you a complete set: CLICK HERE

Description

In this experiment the students use their calorimeter to measure temperature changes during the dissolution process of salts. They realise that the change in temperature depends on the salt. They can calculate the respective molar enthalpy of solution ΔH_m using the measured values.
