Chemistry Coursework Aim, To investigate the factors which alter the rate of the reaction. Planning, In our experiment we will measure the rate of reaction by taking the weight of the solution every ten seconds. This may be altered as we finalise our plans. This method will give us lots of results; this will keep the accuracy of the investigation. We would like to repeat the experiment, this time measuring the rate by measuring the volume of gas given off during a period of time. This will provide lots of useful readings. But because the gas cylinder can only hold, up to 100cc of gas. This may affect the accuracy of the results. Fair Test, During the experiment the temperature of the solution will be altered but we will keep the following points the same... * ...thermometer , * ...amount of hydrochloric acid, * ...amount of limestone, * ...strength of acid, * ...sized pieces of limestone, * ...environment in which the experiment the...
