Module 3.2- Enthalpy Of Neutralisation

Question 1

Definition of enthalpy of neutralisation??

Answer 1

Enthalpy change when an acid and alkali react under standard conditions to form one mole of water

Question 2

Example of neutralisation reaction

Answer 2

HCl+ NaOH -> NaCl + H2O

Question 3

How do you work out enthalpy of neutralisation when 25cm of NaOH and 25cm of HCl

Answer 3

Work out temperature change, specific heat capacity and mass of both substances, multiply all together

Concert joules into kilojoules, then work out number of moles of NaOH, and divide KJ by number of moles
