Temperature change of reacting solutions

To investigate the temperature change of reacting solutions

Do not record the end temperature until you are sure that the temperature of the mixture has stopped increasing

Polystyrene is a thermal insulator

Less heat escapes reaction container

Measurements are more accurate

Repeat the experiment, using a constant volume of hydrochloric acid, but a different volume of sodium hydroxide each time

Draw a graph of temperature change vs volume added

This graph can be used to calculate the volume of sodium hydroxide that would need to be added to attain a given temperature change
