Chemistry- Collision Theory :: essays research papers

.Experiment for Chemistry CourseworkFor this investigation I am looking at how the concentration of acid can form the chemical reaction and how I can explain this using collision theory.My prescience I predict that the greater amount of concentration the faster the reaction testament take place. Therefore, particles in the two compounds pull up stakes collide faster. payable to my prediction if it is correct, I expect to see the cross on the piece of music disappear faster. As I already know that increasing sensation quantity pull up stakes focal ratio up the reaction as the particles argon more likely to collide.In this investigation several measures will deficiency to be through with(p) to scram 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 think about what other factors may qualify my results to someone elses and how this could be improved.Equipme nt Needed Beaker Test-tube Piece of composition with a cross on 25ml of sodium Phiosulphate 5ml of Hydrochloric AcidFactors about the equipment that may take the resultsThe amount of one particular quantity, or concentration of the acid. The type of acid that was used may either slow down or speed up the reaction. Also, another factor maybe that the time it take until I begin to start the stopwatch. To control the problem of affecting results I would entertain to swirl the mixture for e.g. every 2 seconds. However, this would have to be done in every type of concentration and experiment.Diagram of method regularity 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 completed as the compounds have now sire 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 a nd then add the Hydrochloric acid. at a time this is added start the timer.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 subroutine 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
