Table displaying the relationship between temperature and time after 20cm3 of an HCl solution is combined with 20cm3 of a NaOH solution

Time (seconds)

Temperature (ËC)

Qualitative:

* The temperature probe often touched the bottom of the cup.

* Not all the liquid was poured out of the measuring cylinder

* The measuring cylinder had to been rinsed before each measurement meaning it may have been contaminated.

* The two reactants are both clear liquids and when mixed, the result is also a clear liquid. There is no colour change seen in the experiment

* The container of the neutralizing NaOH and HCl rose slightly in temperature, and at the end of the experiment felt slightly warmer than before the experiment

* When stirring, the stirring rod sometimes knocked against the temperature probe

* Small bubbles could be seen to form, most likely as a result from passionate stirring.
