use temperature change to determine olume needed to neutralise
step 1 :
mesure out volumes of acid and alkali, put in a polystyrene cup with a lid and a thermometer (you can put the cup in a beaker for stability
)
step 2:
record maximum temperature reached, repeat this with increasing volumes of alkali
step 3:
plot max temperature against volume of alkali- they will decrease once the alkali is in excess (same amount of energy distrivuted through a greater volume)
step 4 :
where the 2 lines of best fit meet is the volume of alkali needed to neutralise the acid
