Scientific Investigation: How Temperature Affects The Rate Of Reaction Between Magnesium And Hydrochloric Acid!

Extracts from this document...


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.

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.

  1. What effects the rate of a reaction

    takes place, magnesium loses its two electrons to complete its outer shell. It gives one to chorine which completes chlorines outer shell and it gives one to hydrogen to give hydrogen two electrons which completes hydrogen first shell. This releases the hydrogen to be released and therefore to be produced

    good, there is only one anomaly at 50% otherwise this would almost be a straight line graph. Because of this I decided that I should use concentration because the preliminary experiment worked well and so with improvements to the equipment and method and I would be able to produce some hopefully accurate results (like now).

  1. I am investigating the rate of reaction between magnesium and hydrochloric acid.

    We want to investigate this reaction; the purpose of our investigation is to find out the relationship between the mass of magnesium heated and the mass of oxygen, which has reacted with it.

    ml of 1M Hydrochloric Acid + 5 ml of 2M Hydrochloric Acid 1.6M = 2 ml of Water + 8 ml of 2M Hydrochloric Acid 2.0M = 10 ml of 2M Hydrochloric Acid By using these amounts of the different acids and water, the different concentrations can be formed.

  1. What affects the rate of reaction between Magnesium Metal and Hydrochloric acid?

    Another way to change the concentration of the acid is to use a different strength for example instead of using 1M acids we can use 0.50M. Equipment For this experiment we will need * Gas Syringe * Clamp * Side Arm Flask * Measuring Cylinder * Stop clock * Safety

    The second line, from column 7 in 'Obtaining Evidence' (blue x) started very slowly, compared with the other equivalent, then only produced 4cm3 of CO2 between 30secs and 1min 45secs. This was because I was using a smaller bung on the end of my delivery tube that did not create a good enough seal with the boiling tube.
