Introduction

15th July 2005 Carey Butler Coursework Aim My aim is to see how the concentration affects the rate of reaction by measuring the amount of gas produced when reacting with limestone [caco3] with hydrochloric acid [hcl] of differing concentrations. Prediction I think that the more concentrated acid is the more gas will be produced and the reaction will get quicker and quicker. ...read more.

Middle

Diagram This is how my experiment will be set up. Method To start off I would set up my equipment as shown in the diagram, I would then mark my timing point on the gas syringe, then I will then get a fresh packet of limestone chips and add 20ml of acid, then I would put the plug in cork and time whilst 50ml of gas is being produced and mark down my results. ...read more.

Conclusion

49.48 29.73 14.98 Time in seconds Conclusion To conclude this experiment my results have proven my prediction and all of my results were accurate and reliable and in my graph I had no suspect results or anything close to that so I am very pleased with my experiment and if I did it again I would do better, but there are other ways to change the rate of reaction such as temperature, surface area and catalysts. ...read more.
