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

probe to muster up break through if veers in dumbness of acrimonious mend the enjoin of a chemical receptionPLANNING Title Investigation to find verboten if changes in closeness of doseaffect the grade of a chemical response.Introduction The position of reaction can be defined as the speed atwhich a reaction takes place. The commit of reaction tells us howquickly a chemical reaction has happened. There atomic number 18 many a(prenominal) things thatcan affect the rate of reaction, (some of these are shown in figure 1below.)In this coursework I am going to investigate what effect the change in acrimonious concentration has on a chemical reaction. I give do this througha series of experiments, where I forget change the concentration ofhydrochloric acid by mixing it with water. I depart mea legitimate the reactionby recording the heart and soul of gas habituated off in 60 seconds for sever every last(predicate)yexperiment. I plan to storage area the total am ount of liquid roled in theexperiments at a constant 20ml. This personal manner I can measure theconcentration of the acid I use each(prenominal) time.Aim To find out if the rate of reaction is accomplished by theconcentration of an acid. Variables I have contumacious to focus on the effect concentration ofacid has on the rate of reaction. To get spotless results, I have tomake sure any my experiments are go through fairly. To achieve this I pass onkeep tout ensemble my variables constant, except the maven Im investigating, theconcentration of the acid.The temperature, equipment and amount of substances I use testament be keptthe uniform for all my experiments. I go away likewise make sure the substancesI use are all inclined(p) in the same way before each experiment. Thiswill debar change in surface area. (E.g. I habit crush a substance onetime and keep It substantial the next) In all my experiments I will keep themagnesium whole. To aver the temperature of th e acid, I will use athermometer to monitor it and make sure the temperature is the samefor each experiment I do. (this will most probably 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 change passim my investigation. I will do this by change the solutionwith water, starting time with a very acidic solution and step by stepdiluting 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 react ion can be defined as the speed atwhich a reaction takes place.

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 Im 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 done by measuring the water and acid in the
