WebMethod. place a polystyrene cup inside a glass beaker, and (using a measuring cylinder) add 30 ml of hydrochloric acid to the cup. use a thermometer to measure the temperature of the acid, and record this in a table. using a measuring cylinder add 5 ml of sodium hydroxide to the cup. fit the lid and gently stir the solution with the thermometer ... WebThe enthalpy change of a reaction is the energy change that takes place during a reaction per one mole of substance under standard temperature and pressure. Enthalpy changes are normally reported in kJ mol-1. The enthalpy of neutralisation is fairly straightforward to measure as demonstrated in this video from Malmesbury Education.
