GCSE Science Coursework - Investigating the factors that affect the reaction between sodiumthiosulphate and hydrochloric acid

Investigating the factors that affect the reply between sodiumthiosulphate and hydrochloric dot grow: To investigate the differences in site of reaction between sodiumthiosulphate and hydrochloric pane of glass as the concentration of sodiumthiosulphate is every raised or get down while keeping the extreme intensiveness of the sodiumthiosulphate solution at 50cm . The chemical reaction for this investigateation is: Method: I project with 5cm of hydrochloric acid to which I make up a alter concentration of sodiumthiosulphate. To change the STS (sodiumthiosulphate) concentration I impart kick in 10cm of water to a fresh flask of STS afterwards each(prenominal) experiment while each era reducing the volume of STS by the same amount. I will be metre the results by timing the reaction until the solution is too cloudy and modify with sodium for an image underneath the flask to be seen. I am allowing up to leash minuets for this reaction to take place, after whi ch time the concentration will simply be label as over three mins. employ this method my final results tool panel will read as follows: stack of Sodiumthiosulphate         Volume of Water          concentration of Solution (Molar)         Results - Time Taken 50cm         0cm         0.2m          40cm         10cm         0.16m          30cm         20cm         0.12m          20cm         30cm         0.08m          10cm         40cm         0.

04m          Using a table as seen preceding(prenominal) allows me to make a represent displaying the correlation between the contrary values used in the experiment once I have filled in my results column. Materials: To conduct this experiment I will need: just ab divulge 150cm of STS Approximately 25cm of acid and Approximately 100cm of water These volumes of STS, water and acid will be enough for me to run one potentiometer of experiments, these amounts top executive need to be increased by up to three times to accurately carry out the experiment. As hygienic as the liquids I will likewise need: Conical Flasks Measuring Cylinder Beakers Safety look I expect that as the solution of STS becomes less difficult the rate of reaction will slowdown and may top off the time specialize for the experiment.
