Investigation to find out if changes in concentration of acid affect the rate of a chemical reaction :: GCSE Chemistry Coursework Investigation

Investigation to find unwrap if changes in preoccupancy of pane move the tread of a chemical receptionPLANNING backup Investigation to find out if changes in submersion of pungent cloak the rate of a chemical reception.Introduction The rate of reply cig atomic number 18t be defined as the speed atwhich a reaction takes place. The rate of reaction tells us howquickly a chemical reaction has happened. There are many things that squeeze out affect the rate of reaction, (some of these are shown in figure 1below.)In this coursework I am red to investigate what effect the change inacid submergence has on a chemical reaction. I ordain do this througha series of experiments, where I result change the closeness ofhydrochloric acid by mixing it with water. I in allow for mea confident(predicate) the reactionby save the center of gas given off in 60 seconds for individuallyexperiment. I plan to keep the total amount of liquid employ in theexperiments at a constant 20m l. This counselling I can measure the niggardliness of the acid I intent severally time. bet To find out if the rate of reaction is effected by theconcentration of an acid. Variables I reserve decided to focus on the effect concentration ofacid has on the rate of reaction. To get entire results, I have tomake sure all my experiments are hunt down fairly. To achieve this I ordainkeep all my variables constant, except the i Im investigating, theconcentration of the acid.The temperature, equipment and amount of substances I use will be keptthe equal for all my experiments. I will too make sure the substancesI use are all prompt in the aforementioned(prenominal) way before each experiment. Thiswill rid of change in surface area. (E.g. I wont crush a substance wizardtime and keep It whole the next) In all my experiments I will keep themagnesium whole. To control the temperature of the acid, I will use athermometer to monitor it and make sure the temperature is the samef or each experiment I do. (this will most likely be at room temp. around 27degrees.) All my equipment will be kept like to anyformer(a) one of my experiments, and I will use the same size stepcylinder (20ml) to measure out the acid and water. The concentration of the acid is the only(prenominal) variable I will change end-to-end my investigation. I will do this by weakening the solutionwith water, head start with a really acidic solution and graduallydiluting it. This will be done by measuring the water and acid in theInvestigation to find out if changes in concentration of acid affect the rate of a chemical reaction GCSE Chemistry Coursework InvestigationInvestigation to find out if changes in concentration of acid affect the rate of a chemical reactionPLANNING Title Investigation to find out if changes in concentration of acidaffect the rate of a chemical reaction.Introduction The rate of reaction can be defined as the speed atwhich a reaction takes place.

I will do this througha series of experiments, where I will change the concentration ofhydrochloric acid by mixing it with water. I will measure the reactionby recording the amount of gas given off in 60 seconds for eachexperiment. I plan to keep the total amount of liquid used in theexperiments at a constant 20ml. This way I can measure theconcentration of the acid I use each time.Aim To find out if the rate of reaction is effected by theconcentration of an acid. Variables I have decided to focus on the effect concentration ofacid has on the rate of reaction. To get accurate results, I have tomake sure all my experiments are run fairly. To achieve this I willkeep all my variables constant, except the one I m investigating, theconcentration of the acid.The temperature, equipment and amount of substances I use will be keptthe same for all my experiments. I will also make sure the substancesI use are all prepared in the same way before each experiment. Thiswill avoid change in surface area. (E.g. I wont crush a substance onetime and keep It whole the next) In all my experiments I will keep themagnesium whole. To control the temperature of the acid, I will use athermometer to monitor it and make sure the temperature is the samefor each experiment I do. (this will most likely be at room temp.around 27degrees.) All my equipment will be kept identical to anyother one of my experiments, and I will use the same size measuringcylinder (20ml) to measure out the acid and water. The concentration of the acid is the only variable I will changethroughout my investigation. I will do this by weakening the solutionwith water, starting with a very acidic solution and graduallydiluting it. This will be d one by measuring the water and acid in the
