Chemistry- Collision Theory :: essays research papers

.Experiment for Chemistry CourseworkFor this investigation I am looking at how the concentration of acid give the bounce change the reaction and how I can explain this using collision theory.My Prediction I predict that the greater fare of concentration the faster the reaction will take place. Therefore, particles in the two compounds will collide faster. Due to my prediction if it is correct, I have to see the go bad on the paper disappear faster. As I already know that increasing one quantity will revivify up the reaction as the particles are more likely to collide.In this investigation several measures will need to be do to ready sure that the results I get will be precise. From the planed method I can work out what will need to be done to achieve the best results possible. I will also need to cogitate about what other divisors may vary my results to someone elses and how this could be improved.Equipment Needed Beaker Test-tube Piece of paper with a beat on 25ml of a tomic number 11 Phiosulphate 5ml of Hydrochloric AcidFactors about the equipment that may affect the resultsThe amount of one especial(a) quantity, or concentration of the acid. The slip of acid that was used may both slow down or speed up the reaction. Also, another factor maybe that the era it take until I begin to start the stopwatch. To retain the problem of affecting results I would have to swirl the mixture for e.g. any 2 seconds. However, this would have to be done in every type of concentration and experiment.Diagram of methodMethod Draw a cross on a piece of paper and place a beaker on top of the paper. This is because once the cross disappears I know the reaction has established as the compounds have now become one solution.Secondly, measure as accurately as possible 25ml of Sodium Phiosulphate and 5ml of Hydrochloric acid. Thirdly, pour the measured amount of Sodium Phiosulphate into the beaker and then add the Hydrochloric acid. Once this is added start the caden cer.Finally, once the cross has completely disappeared stop the clock and make a not of the time it took for the mixture to become one.NOTE This procedure was produced with different concentrations. This was so that I could see whether the concentration had an affect on experiments time limit. ResultsBefore doing our experiment we saw a trail run on the computer known as
