Rates of reactions coursework (gcse) rate of reaction the effect of concentration on the reaction between magnesium and hydrochloric acid mg(s) + 2hcl(aq) mgcl2(aq) + h2(g) aim: in this experiment i am going observe and record the reaction between magnesium and different concentrations of hydrochloric acid.
Hi everyone i just had a question for you- im in year 11 at the moment, and im doing additional science- ocr 21st century im doing my coursework at the moment, and the people doing the same course as me, or doing triple science with the same board, will. Gcse chemistry (single science) chemistry is the study of the composition, behaviour and properties of matter, and of the elements of the earth and its atmosphere part of science. Rates of reaction gcse coursework chemistry 2004 aim in the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride. Chemistry gcse coursework rates of reaction essay science coursework- rates of reactions introduction investigating how the concentration of sodium-thiosulphate (sts) and hydrochloric acid (hcl) affects the rate of reaction in the experiment.
Chemistry practical investigation preparation which involves adding different concentrations of a substance to another substance and then take note of the different rates of reaction, if any difference is to be seen if a difference is seen then we can come to the conclusion that concentration does have an effect on the rate of a reaction. The smaller the chips, the bigger the surface area and the faster the reaction alternatively, you could vary the concentration of the acid using 04m, 08m 12m, 16m and 2m the more concentrated the acid, the more frequently the acid particles collide with the marble and therefore the faster the reaction. In order to get maximum marks in this coursework it is vital that you discuss all factors which affect the rate of a reaction these include: temperature. In a chemical reaction, the reactant particles can only react with each other when they bump into one another according to collision theory when molecules collide bonds between their atoms can. To be confident about the reaction rates calculated for the lab large inaccuracies could make it difficult to see the trends necessary for the understanding of this experiment.
