Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid Essay

Rates of Reaction - Sodium Thiosulphate and Hydrochloric acidIn this piece of coursework, I will vignette how concentration affectsthe rate of reaction. I will do so by timing the reaction of SodiumThiosulphate with an acid. In this coursework, I will include backdrop knowledge, forecasting, safety, results, calculations,graphs, an analysis, proof and an evaluation. In my evaluation Iwill comment on how reliable my results were and how I could begetim proved my coursework in any possible way.The commentary of rate of reaction is The speed at which a chemicalreaction takes place. The factors that affect the rate of reaction be Use of a accelerator pedal Temperature Surface area ConcentrationI will be investigating Concentration in this experiment. In a higherconcentration there are more Sodium Thiosulphate particles. This meansthere is a higher number of concussions which will have enough energyto react. This wees the rate to increase. The time it takes for a mixed bag to take place can be measured and can be estimated. For areaction to take place 2 reactants must collide and the collision musthave enough energy.PredictionI predict that as the concentration of the Sodium Thiosulphateincreases the rate of reaction will increase. This can be proved byrelating to the collision theory. I predict that as concentration isincreased the amount of time taken for the reaction is halved.Safety IssuesThere are legion(predicate) safety issues that need to be considered while doingthis experiment. These include Wearing safety goggles at all times. If acids or any other chemicals are spilt, they would cause serious damage to the skin and eyes. Ties and long hair should be kept away from the experiment. If an accident ... ... my evidence of this experiment is reliable because I did itwith precision and carried it unwrap carefully. I thought that I mighthave some anomalies but there were not any. I can prove this by usingmy prediction earlier in the experiment. I sai d that as concentrationis increased the amount of time taken for the reaction is halved. Iwould have been perfectly repair but I made a mistake while measuring.To improve my results, I would use a wider range of concentration anddifferent acid solutions. This would help me to find a pattern andcome to a firm conclusion.Overall I think that this experiment was a success as I have provedthat concentration does affect rate, and I have also found that whenthe concentration is doubled the rate of reaction is halved. To draw afirm conclusion I would need to get more results, less inaccuraciesand better measuring methods.
