Exploring Factors That Affect The Rate Of A Chemical Reaction Involving Magnesium And Hydrochloric Acid

1581 words - 6 pages

What factors affect the rate of this chemical reaction:
Magnesium + Hydrochloric Acid  Magnesium Chloride + Hydrogen
Mg (s) + 2HCl (aq)  MgCl2 (aq) + H2 (g)

Prediction

I think that my results will show that the hydrochloric acid with a molarity of 2 will finish reacting the quickest because it is the strongest hydrochloric acid and I predict that the slowest experiment to finish reacting will be the 0.4 molar strength of hydrochloric acid. I think that the results will go slower and slower the nearer they are to the 0.4 strength of hydrochloric acid. The reason that the experiment with hydrochloric acid at 2 molar will dissolve the magnesium ribbon faster is because it is of a stronger concentration and so the molecules in the hydrochloric acid move faster and so react with the magnesium ribbon quicker.
Strategy
Some factors that could cause the rate of reaction to vary are simple things like temperature. The temperature could affect things like the rate of successful collisions.
The method that I chose was downward displacement of water. The main reason that I chose this was because that is really easy to use and very clear to collect my results. Also our solution produces a soluble gas so the reaction will work perfect.
Other methods available consisted of timing how long it took for the magnesium to disappear. We would place the liquid and the magnesium in a flask and start the timer, one reason we chose not do this is we won’t precisely know when the reaction is finished. Plus people might have different opinions of when the magnesium has disappeared. Another is timing how long it takes for a solution to turn cloudy. We would again place the liquid and the magnesium in a flask and start our timer, the reason we did not choose this method is because we would need a insoluble liquid produce whereas ours has a soluble gas so it would not turn cloudy, making the test non-practical and ineffective.

I predict that the rate of reaction will decrease as the concentration of the hydrochloric acid decreases. I have predicted this because the higher the concentration of acid the more chance of collisions with magnesium therefore the rate of reaction will decrease as the concentration decreases.

I am going to keep the fair test buy keeping the amount of magnesium the same for each different concentration of acid. The changeable variables are, hydrochloric acid and water.

The apparatus that is going to be used for this experiment is:
A conical flask
A gas syringe
A measuring cylinder
Stop clock
A clamp
Methodology
The first thing that we shall do is to prepare our work area where we will be doing the experiment, clear anything that could cause an obstruction or any risk. The next thing to do is to simply gather together, and not set up, all equipment that we shall need. Next we will set up the equipment that we have just gathered together, as the diagram above shows.

Once this is done we will take the...
