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

Rate of reaction of Magnesium and HCL In order to find a good set of results for this experiment I need to decide 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 give evidence 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. I also need to think about how i am going to measure the speed of the reaction in order to get a table of reliable results. Plan  · Equipment needed for experiment:  · Bowl  · Hcl  · 2 Measuring cylinders (1 big/1 small)  · Mg strips  · Flask  · Beaker  · Tube  · Stop clock  · Goggles  · Beehive shell Step One All of the above equipment must be gathered. Step Two The Beehive shell sould be placed in the centre inside the bowl, then the bowl is to be filled up with water until the beehive shell is covered.Then the big measuring cylinder is to be filled to the top with water and then turned upside down onto the beehive shell. Step Three The 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 is connected to the flask) is placed into the cylinder. Step Four Then the flask needs to be filled with 20 cm3 Hcl acid, the acid is measured in a measuring tube and then poured in, once the flask is filled the magnesium strip is to be placed inside. In order to get the Magnesium strip as accurate as possible it is to be measured with a ruler to the size in which desired. Step 5 As soon as the magnesium strip touches the acid it starts to react, so the plastic plug should be put on to the flask quickly, then start the stopclock and record the amount of gas every 10 seconds. One person should read the results at eye level to the tube, so they can get an accurate reading, and another person should note down the times whereas one keeps there eye on the time. Things that will effect the rate of reaction  · Concentration of Hcl  · Surface area of Magnesium  · Temperature of reaction  · Catalyst  · Length of Magnesium  · Volume of Hcl The concentration can be increased or decreased to effect the rate of reaction. The higher the concentration, the more particles, therefore a higher rate of reaction. The surface area of magnesium can effect the rate of reaction. The larger the surface area, the faster the reaction will be as the
