Due to the number of different experiments, the uncertainties have been recorded and calculated in several tables below.\\\\  It is clear that there are no large uncertainties in the results, with the greatest being in the volume of the Sodium Thiosulfate. This is because a smaller volume was used than the other reactants. A digital temperature probe could have reduced the uncertainty in the temperature, but considering the fact that it is difficult to keep the temperature constant it would have no impact on the reliability of the results.   \\\\The volume of Starch has been omitted from uncertainty calculations. This is because it has a negligible effect on the final time recorded; it is an indicator, with the only effect being that it keeps the volume of the solution used constant. A teat pipette was used in each case to measure out 1cm\textsuperscript{3}, which would have led to a high uncertainty. If the experiment were to be repeated, it would be easy to set up a burette of starch and use this, however it would have little effect on the accuracy of the results.  \\\\\\\\ \\\\\\  \begin{table}[!htb]  \centering  \caption{A table to show the uncertainties in the standard solutions made up.
