ASSIGNMENT
REACTION BETWEEN MARBLE CHIPS AND HYDROCHLORIC ACID
Labelled Diagram
Draw a diagram showing the apparatus as set up. Remember the diagram enables someone else to repeat what you did and can be used to support your description in the method. Use the apparatus sheets to ensure you are using the accepted diagrammatic form of the apparatus.
Results
Wherever possible, record your results in a table. Tables and figures should be presented as they would appear in a learned journal, use Journal of Physical Chemistry as a guide. Be sure to correctly state units and quote numbers to an appropriate number of significant figures. Use figure captions. Show fully all steps in any calculation.
Describe any observations. (20 marks)
Graphs Where these are required, they should include a caption, number, and axis must have labels and units. Equations Include the balanced equations for all the reactions observed.
Discussion and Conclusion
Describe the observed trend in the results and then explain these using your scientific knowledge, compare with reported literature. (20 marks)
