What is the enthalpy change of neutralisation definition? How is heat energy change calculated? What are the sources of error for enthalpy change of neutralisation? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 2 – WCH12, but it can also be used for all UK exam boards. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides (which are best opened on Microsoft PowerPoint) is as follows:

Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – Definition of a thermometric titration
Slide 4 – Definition of enthalpy change of neutralisation
Slide 5 – example equations for the enthalpy change of neutralisation
Slide 6 - diagram of experimental setup for enthalpy change of neutralisation
Slides 7 – 9: Method for enthalpy change of neutralisation experiment (feel free to do the practical with your students!) Print slides 7 – 8 for your students
Slides 10 – 16: Worked example, using Q = mcΔT and ΔH=Q÷n
Slides 17 – 19: Mini plenary exam style questions with answers that animate onto the screen when you click
