Rates of Reaction - Magnesium and HCL :: GCSE Chemistry Coursework Investigation

Rate of reaction of Magnesium and HCLIn order to find a good tick of results for this experiment I need todecide what molars i am issue to use, and also how i allow make them.Once i drop found which molars i would like to use i will fatherevidence of why i have chosen them, i will also decide which variablesare important to considerm e.g The Values of Mg, great deal of acid. Ialso need to think about how i am sack to measure the speed of thereaction in order to get a table of reliable results.Plan Equipment needed for experiment Bowl Hcl 2 Measuring cylinders (1 giant/1 small) Mg strips Flask Beaker Tube forgo clock Goggles Beehive boomStep One any of the above equipment must be gathered.Step TwoThe Beehive shell sould be put in the centre inside the public treasury, becausethe bowl is to be change up with water until the hive shell iscovered.Then the big measuring cylinder is to be filled to the topwith water and then turned upside down onto the beehive shell.Step Thr eeThe render should be placed directly over the hole in the beehive shell,where the pipework(which goes through the hole in the beehive shell and isconnected to the flask) is placed into the cylinder.Step FourThen the flask needs to be filled with 20 cm3 Hcl acid, the acid ismeasured in a measuring tube and then poured in, once the flask isfilled the magnesium strip is to be placed inside. In order to get theMagnesium strip as accu footstep as possible it is to be measured with a dominion to the size in which desired.Step 5As soon as the magnesium strip touches the acid it starts to react, sothe plastic plug should be put on to the flask quickly, then start thestopclock and record the follow of gas every 10 seconds. One personshould read the results at heart level to the tube, so they can get anaccurate reading, and another(prenominal) person should note down the timeswhereas one keeps there eye on the time.Things that will centre the rate of reaction Concentration of Hcl ascen d area of Magnesium Temperature of reaction Catalyst Length of Magnesium Volume of HclThe concentration can be increased or decreased to effect the rate ofreaction. The higher the concentration, the more particles, thereforea higher rate of reaction.The surface area of magnesium can effect the rate of reaction. The big the surface area, the faster the reaction will be as the
