.Experiment for Chemistry Coursework

For this investigation I am looking at how the concentration of acid can change the reaction and how I can explain this using collision theory.

My Prediction: I predict that the greater amount 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 expect to see the cross on the paper disappear faster. As I already know that increasing one quantity will speed up the reaction as the particles are more likely to collide.

In this investigation several measures will need to be done to make sure that the results I get will be precise. From the planned
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 vary my results to someone else's and how this could be improved.

Equipment Needed:
· Beaker
· Test-tube
· Piece of paper with a cross on......
