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

Rate of reaction of Magnesium and HCLIn order to find a good set of results for this examine I need todecide what molars i am going to use, and also how i will make them.Once i have found which molars i would like to use i will giveevidence of why i have chosen them, i will also decide which variables are important to considerm e.g The Values of Mg, Volume of acid. Ialso need to think about how i am going 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 long/1 small) Mg strips flaskful Beaker Tube Stop clock Goggles beehive shellStep OneAll of the above equipment must be gathered.Step TwoThe Beehive shell sould be placed in the centre inside the bowl, thenthe bowl is to be filled up with water until the beehive 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 ThreeThe tube should be placed directly over the hole in the beehive shell,where the tube(which goes through the hole in the beehive shell and isconnected to the flask) is placed into the cylinder.Step quaternionThen 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 accurate as possible it is to be measured with aruler to the size in which desired.Step 5As soon as the magnesium strip touches the acid it starts to react, sothe fictile plug should be put on to the flask quickly, then start thestopclock and record the amount of gas every 10 seconds. One personshould subscribe the results at bosom level to the tube, so they can get anaccurate reading, and another person should note down the timeswhereas one keeps there eye on the time.Things that will effect the rate of reaction Concentration of Hcl Surface empyrean of Magnesium Temperature of rea ction Catalyst Length of Magnesium Volume of HclThe assimilation 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. Thelarger the surface area, the faster the reaction will be as the
