Preparation We did several pilot tests to see which the best experiment to do was and what the best way to do it was.Chemistry Coursework.An Investigation into the effects of concentration on a reaction. We chose this method.CHEMISTRY COURSEWORK ON RATES OF REACTION. Aim: I am going to carry out an investigation measuring the rate of reaction between hydrochloric acid and magnesium. The independent variable will be the molar of the hydrochloric acid; I will be diluting it with water to change the concentration.Equipment: a gas syringe, rubber bung, conical flask, stand, clamp, 25ml hydrochloric acid, 2g medium sized calcium carbonate pieces, and a stopwatch. Method; 1) The gas syringe should be set up horizontally by an attachment to the stand, by the clamp. The tubing should be positioned well on the rear end of the gas syringe.WARNING: Your write-up must be your work produced from your study and your experiments. This web page is meant to teach you how to tackle an coursework e.g. on rates, it is not meant to be copied and the details filled in! Your coursework write-up must expressed in your language and expressed at ‘your scientific level’.GCSE CHEMISTRY RATES OF REACTION COURSEWORK. … Rates of Reaction Coursework Chemistry … that form the base of your experiment.<span class=”news_dt”>02.05.2007</span> · i am doing a chemistry coursework, and i wanted to know what the percentage error for the gas syringe is?
