Science Coursework Factors Affecting the Rate Of A Reaction Aim: The aim of our experiment is to find out the effect of Hydrochloric acid concentration on rate of reaction with magnesium. What I Already Know: I already know that when hydrochloric acid reacts with magnesium it creates magnesium chloride and gives off hydrogen gas. I also know due to my preliminary experiments that this is an exothermic reaction, which means that heat is given out during the reaction. Volume of acid (cm3) Temperature increase after the reaction (degrees C) 10 15 20 14 40 7 Using these results I can choose the volume of acid I am going to use. If I used 10cm3 the temperature given off might affect my results. From the results I have collected I can observe that I should use between 25cm3 and 40cm3 in order to avoid the heat affecting my reaction. Also due to this experiment I have discovered that as you increase the volume...
