Enthalpy of Neutralisation Between HCl and NaOH Essay 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.
