Prescribed practical C3 - Temperature changes during a reaction
An acid will usually release heat when it reacts.
In this reaction we are going to react an acid with an alkali and measure the temperature change during the reaction.
The acid will react to produce a salt and water 鈥 no gas is produced. Also, in this reaction there is no colour change. However, the pH will change 鈥 you could measure this as described in the previous reaction.
