Concentration sodium thiosulphate coursework

Sodium thiosulfate medical use It is used as an antidote to cyanide poisoning. For this purpose it is used together with sodium nitrite. It is used in the management of extravasations during chemotherapy.

I so tried 3cm3 Na thiosulphate with 17cm3 distilled H2O, which went absolutely good and I decided to utilize low sums of Na thiosulphate because I wanted to cognize how long it took the lowest to respond with HCl besides I wanted to cognize the highest and lowest that I could utilize for my tabular array of consequences.

Using the graphs, I can do a decision from my experiment.

I can see that with the clip graph as the concentration increased the clip taken for the reaction to take topographic point decreased. There is one variable that has affected the consequences and that is the temperature which may hold changed somewhat, giving an wrong consequence.

This is because when the temperature is increased the atoms will hold more energy and so do the atoms move faster. Therefore they will clash more frequently and with more energy. Atoms with more energy are more likely to respond successfully and hits between responding atoms are accordingly more likely to take topographic point, as stated in the hit theory.

As the concentration of Na thiosulphate additions, the sum of clip lessenings because the reaction is acquiring faster. This is because the higher the concentration, the more atoms there are, so there is a bigger opportunity of successful hits go oning between Na thiosulphate and hydrochloric acid.

When the concentration of the hydrochloric acid was lower the reaction took longer, this is because there were fewer atoms, so there was a smaller opportunity of successful hits go oning.

From my consequences I noticed that as the concentration of sodium thiosulphate increased, the rate of reaction besides increased. This is because the more atoms there are in the volume of Na thiosulphate the faster the reaction will take topographic point, since there is a greater opportunity of a Na thiosulphate atom hitting a hydrochloric acid atom.

This confirms my theory which states that increasing the concentration of the reactants and increasing the temperature causes more hits and hence more successful hits which increases the rate of reaction.

To better the truth of my consequences, if I was to make the experiment once more, I would utilize a burette to mensurate the right volumes of Na thiosulphate solution and hydrochloric acid.

I realised that I may non hold been precise plenty when utilizing the measurement cylinder. If I did the experiment once more, alternatively of visually look intoing when the cross has disappeared, I would utilize a light metre to mensurate the sum of light left in the reaction.

When the reaction turns cloudy, the light metre would observe it. This would give more just and precise consequences. I would besides utilize a H2O bath to maintain the mixture the same temperature.

The room temperature may hold been different on the yearss I did the experiment so this could do anomalousnesss. I am confident humor my consequences because We measured everything carefully excessively, to guarantee better consequences and we besides found that the higher the concentration of Na thiosulphate the faster the reaction.

Overall I think my experiment was a success.
