The effect of concentration on the rate of reaction between hydrochloric acid and magnesium ribbon
Plan
The rate of reaction can be affected by these factors,
* Temperature
* Concentration
* Size of surface area
* And by adding a catalyst
I have chosen to investigate the effect of concentration.
This will be done be investigated by diluting acid and timing how long it takes the same amount of magnesium ribbon to dissolve. I will obtain evidence by diluting the acid with 5ml of water each time, then timing how long it takes the magnesium ribbon to dissolve fully. The experiment will be done 6 times. This experiment will be repeated 2 times then the average of the two will be worked out. To make this a fair test the same amount of magnesium ribbon must be used. I have 60 cm of ribbon to use; each time the experiment is done I will use 4cm. This leaves 12cm to check any anomalous results. Also to keep a fair test the temperature must stay the same, the fore the experiments will all be carried out at room temperature. The apparatus I intend to use are as follows; Stop Clock, 50ml measuring cylinder and a 250ml-measuring beaker.
