Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid Essay

Rates of Reaction - sodium Thiosulphate and Hydrochloric acidIn this piece of coursework, I will study how absorption preservesthe prise of reaction. I will do so by timing the reaction of SodiumThiosulphate with an acid. In this coursework, I will includebackground knowledge, prediction, safety, results, calculations,graphs, an analysis, conclusion and an evaluation. In my evaluation Iwill comment on how reliable my results were and how I could stoolimproved my coursework in any possible way.The definition of respect of reaction is The speed at which a chemicalreaction takes blot. The factors that affect the rate of reactionare Use of a gun Temperature Surface area ConcentrationI will be investigate Concentration in this experiment. In a higher(prenominal) stringency in that respect are more Sodium Thiosulphate particles. This meansthere is a higher number of collisions which will have enough energyto react. This causes the rate to increase. The while it takes for achange to take place can be careful and can be estimated. For areaction to take place 2 reactants must collide and the collision musthave enough energy. foretellingI 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 many safety issues that affect 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 adept 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 reveal carefully. I thought that I mighthave some anomalies merely there were not any. I can prove this by utilisemy prediction 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 fall away 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 and hump 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 ingest to get more results, less inaccuraciesand better measuring methods.
