Enthalpy of Neutralisation Between HCl and NaOH EssayTable displaying the relationship between temperature and time after 20cm3 of an HCl solution is combined with 20cm3 of a NaOH solutionTime (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.
