Measure enthalpy
WebJan 7, 2024 · To use calorimetric data to calculate enthalpy changes. Heat Capacity We now introduce two concepts useful in describing heat flow and temperature change. The heat … WebThe enthalpy change is the ‘enthalpy change of hydration’. It can’t be measured directly as we cannot physically measure how much energy is released when five moles of water react with one mole of copper (II) sulfate. Both routes end up with a solution of copper (II) sulfate.
