Investigate the rate of reaction with magnesium and different concentrations of hydrochloric acid - Plan

Extracts from this document...

Introduction

I am going to investigate the rate of reaction with magnesium and different concentrations of hydrochloric acid. In order to carry out the experiment, I will need the correct apparatus which are: * Goggles * Stop clock * Beaker * 30 cm3 measuring cylinder * 5x70mm magnesium ribbons * 1, 1.5, 2, 2.5, 3 mol./dm3 hydrochloric acid * Gas syringe Next, the apparatus has to be set out, which should look like this: Key Factors: The magnesium has to be sanded to remove any oxide on the ribbon. ...read more.

Middle

The hydrochloric acid must be measured preciously because the tests won't be reliable. Next, the hydrochloric acid is poured into the beaker. Once the hydrochloric acid is in the beaker, one person checks the time (every 10 sec.) and the volume of hydrogen produced. The other person puts the magnesium ribbon (which is folded into eight sections to provide a large surface area) into the hydrochloric acid. To ensure no hydrogen escapes, the person must check whether there are any leaks around the top of the beaker, which leads to reliable results. ...read more.

Conclusion

Fair Test: Variable Constant Concentration of hydrochloric acid Volume of acid (30 cm3) Length of magnesium ribbon (70mm) Type of acid Surface area of magnesium ribbon (folded eight times) Temperature of environment Prediction: I predict the more amount of concentration, the faster the reaction and the more amount of hydrogen produced. I think the reaction is going to be faster and more hydrogen will be produced because the particles are crowded and will collide with each other more often, resulting in an increased number of successful collisions per second. ?? ?? ?? ??

    The factors which may affect the rate of reaction are as follows: � Concentration of acid This could affect the rate of reaction because the higher the concentration of the acid then the more acid particles so there would be meaning collisions per second this will then lead to more successful collisions per second.

    This allows me to change the concentrations, but keep all of the other variables the same, mainly the volume of the acidic liquid. I have decided to make six separate experiments, one for each different concentration, so that there is a wide range of results for me to analyse and evaluate.

    When getting the hydrochloric acid we shall take one container full and if we need anymore we merely ask for some more, and we shall only get the magnesium ribbon when we need it, this is not only for safety reasons but also we shall be able to measure out the desired amount there and then.
