A student wants to find out whether the temperature rise in a neutralisation reaction depends on the concentration of the acid used.
The student is given dilute hydrochloric acid at four different concentrations, sodium hydroxide solution, polystyrene cups with lids, a measuring cylinder and a thermometer.
Plan an investigation the student could carry out.
85 exam-style questions on AQA GCSE Chemistry 5.1 Exothermic and endothermic reactions, covering 5.1.1 Energy transfer during exothermic and endothermic reactions, 5.1.2 Reaction profiles, and 5.1.3 The energy change of reactions. Each one has a worked solution and a mark scheme showing where the marks go.
