Chemistry Coursework: PLAN
Investigate the rate of reaction between different concentrations of hydrochloric acid with metal carbonates using calcium carbonate as the example.
Apparatus
For this experiment I will require the following apparatus;
The apparatus will be set up as shown in the diagram above. I will begin timing each experiment when the necessary hydrochloric acid, water and calcium carbonate quantities are in the conical flask – and the top is sealed. Timing will stop once 50cm3 of gas has appeared in the measuring cylinder.
Concentrations
The concentrations I will be using during my experiment are as follows;
Using these concentrations will mean that a good range of results will be obtained, therefore making this experiment more reliable and easier to draw conclusions from. The calcium carbonate that is used will be in granules because:
