By doing this investigation I want to find out what effect different temperatures have on the rate of reaction between magnesium and hydrochloric acid.

Introduction

Introduction to Rates Rate is a measure of how fast or slow something is. It is a measure of the change that happens in a single unit of time. Rates can be measured in 2 different ways: (a) The rate of disappearance of a reactant. (b) The rate of appearance of a product. Some reactions are very fast and others are very slow. Plan By doing this investigation I want to find out what effect different temperatures have on the rate of reaction between magnesium and hydrochloric acid. The word and symbol equations for this reaction is as below: Magnesium + Hydrochloric acid = Magnesium chloride + Hydrogen Mg + 2HCL = MgCl2 + H2 There are a number of factors, which may influence the investigation in various ways, these include: * Type of Magnesium used * Temperature of reaction * Concentration of Hydrochloric acid * Concentration of Magnesium * Amount of Magnesium * Amount of Hydrochloric acid (volume) * Addition of a catalyst * What scale of reaction * Surface area of Magnesium * Whether to stir the mixture during the reaction or not These factors are all very important because they all can affect the rate of the reaction in different ways. ...read more.

We are also working with a Bunsen burner; we need to be aware of it and to make sure that we leave it with an orange flame so that others can see it. We also need to take into consideration all of the other basic lab safety precautions. Method 1) Measure out 20ml of acid and put into the boiling tube. 2) Set-up apparatus as above and heat the beaker and its contents to the desired temperature. 3) When the acid is at the correct temperature lift it from the water and place into the test tube rack. Carefully weight out 0.1grams of magnesium using the weighing boat and the top ban balance. 4) Add the magnesium into the boiling tube containing the acid. 5) Start the stopwatch and watch until all the effervescence has stopped. 6) Stop the stopwatch when the effervescence has stopped. 7) Record result. 8) Repeat another two times at the same temperature, and then move on to the next temperature. Results As we do the investigation the results table, which we will draw out before we start, will be filled in as we collect the data. Appropriate graphs will be drawn later on as a way of analysing our data. ...read more.

Conclusion

*Use a water bath, which has a thermostat, which would have been easier to keep the acid at a constant temperature. *We could also use a larger boiling tube because as we added the magnesium some of it got stuck to the sides of the tube, therefore not reaching the acid. Because of this sometimes not all the magnesium reacted with the acid. *More repeats could be carried out to qualify the findings. These could be done under different conditions to see how the reactions react under a colder or hotter environment. *I could also use a different form of magnesium i.e.) powdered magnesium, which would have a different surface area. *I could also investigate whether or not the rate of reaction will decrease as the temperature decreases. *I could also investigate whether the same patterns occur if I used a different acid and a different metal. I could further my investigation by investigating how other factors influence the rate of reaction i.e.) Concentration, catalysts etc. I found that all of my results were accurate and I found that all of the results fitted in with the patterns shown by the graphs. In conclusion from this experiment I have found that the rate of a reaction increases as the temperature increases. ...read more.

    As the temperature is increased the particles move faster since they have more energy. This means that they are colliding more often and more of the collisions have enough velocity to cause a reaction. Since there are more collisions the chemical reaction takes place faster.
