Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid Essay

Rates of reply - Sodium Thiosulphate and Hydrochloric acidIn this piece of coursework, I will pick out how niggardliness affectsthe rate of response. I will do so by timing the reaction of SodiumThiosulphate with an acid. In this coursework, I will holdbackground knowledge, prediction, safety, results, calculations,graphs, an analysis, conclusion and an evaluation. In my evaluation Iwill view on how good my results were and how I could nurtureim proved my coursework in whatsoever possible way.The definition of rate of reaction is The speed at which a chemicalreaction takes define. The factors that affect the rate of reaction are Use of a catalyst Temperature Surface area ConcentrationI will be investigating Concentration in this experiment. In a higherconcentration there are more Sodium Thiosulphate particles. This heart and soulthere is a higher number of collisions which will have plenteous energyto react. This ca applys the rate to increase. The time it takes for ach ange to take place tooshie be measured and can be estimated. For areaction to take place 2 reactants essential 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 is change magnitude the amount of time taken for the reaction is halved.Safety IssuesThere are many safety issues that need to be considered while doingthis experiment. These include wearing safety goggles at all times. If acids or any some other chemicals are spilt, they would cause serious damage to the skin and eyes. Ties and long hairsbreadth 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 out carefully. I thought that I big businessmanhave some anomalies but there were not any. I can prove this by usingmy pr ediction earlier in the experiment. I said that as concentrationis increased the amount of time taken for the reaction is halved. Iwould have been perfectly right 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 hearty conclusion.Overall I think that this experiment was a success as I have provedthat concentration does affect rate, and I have also set up that whenthe concentration is doubled the rate of reaction is halved. To draw afirm conclusion I would need to get more results, less inaccuraciesand bust measuring methods.
