Extracts from this document...

Introduction

Scientific Investigation: How Temperature Affects The Rate Of Reaction Between Magnesium And Hydrochloric Acid! Planning I'm planning on investigating how temperature effects the reaction between magnesium and hydrochloric acid, the experiment will show whether the reaction will speed up or slow down with the change in temperature. Temperatures will range from room temp up until 70 degrees. The investigation will be a fair test because all quantities will remain the same for each test, each test will use the same amounts of hydrochloric acid and same size of magnesium, also the concentration of the acid will also not be changed. APPERATUS; * Conical flask * Bunsen Burner * Thermometer * Tri-pod * Protective matt * Stopwatch * Gauze * Measuring jug * Goggles Whilst doing the experiment there are many things that will have to remain the same in order to keep the tests fair, these include amounts and measurements as well as concentration and size and shape of the magnesium e.g. ...read more.

feel that the test will show me that as the temperature increases the time for the reaction to completely take place will decrease. I came to my prediction through seeing in past tests and experiments throughout the year that temperature has increased many rates of reaction, so I believe the same will occur in this test. Data The results I obtain will be stored in a table; the results will be recorded on both temperature and time enabling me to give a clear graph showing my results. I will record the rate at which the magnesium reacts in hydrochloric acid at temperatures of; room temp (27), 40, 50, 60, 70 degrees, at each temperature, magnesium will be added to the acid, and the rate at which it takes to fully react and disappear will be recorded.

Conclusion

60degrees could of actually been over and at 63degrees. Other factors affected the investigation; these factors are minor things such as delays in timing response and slight different sizes of magnesium. Many things, not massive factors, but very minor factors give slightly non accurate answers. These inaccuracies are unavoidable and are due to human abilities, factors couldn't have been made any more accurate unless done by machine. Evaluation I am pleased with the investigation results and the way, in which the tests were taken, even though the tests worked well they still were not completely accurate. All results matched my prediction and all results point towards my prediction. My results support my conclusion, as the temperature of hydrochloric acid increases the rate at which the magnesium react decreases. The results show clearly this conclusion and also once again back up my prediction. To improve my investigation I would carry out the test double the amount of times and at more frequent temperatures, I would also use a water bath to keep the temperature of the acid the same throughout the reaction. ...read more.

    This is why I chose to triplicate my results. Although to improve this experiment I could also repeat the experiment many more times, this would improve the accuracy in the results. Another point was that the time from dropping the magnesium, to pressing the stopwatch, there was a small delay.

    good, there is only one anomaly at 50% otherwise this would almost be a straight line graph.
