Question 2
Part (a)
(i) Measure 200cm3 of water into the beaker.
(ii) Heat the water until it boils steadily for about 2 minutes.
(iii) Read and record the boiling point bo.
(iv) Add table salt of mass M=10.0g to the boiling water and stir continuously until another boiling point bi is attained.
(v) Read and Record bi.
(vi) Evaluate θi = (bi – bo )
(vii) Using the same mixture, repeat the procedure four more times by adding 10.0g of salt each time to give the cumulative mass Mi of salt as 20g, 30g, 40g, and 50g.
(viii) In each case, allow the mixture to boil steadily for at least 2 minutes, then read and record the boiling point bi.
(ix) Tabulate your readings.
(x) Plot a graph with Mi on the vertical axis and θi on the horizontal axis.
(xi) Determine the slope, s, of the graph.
(xii) State two precautions taken to ensure accurate results.
(xiii) Define the boiling points of a liquid.
(xiv) What effect do impurities have on the boiling point of a liquid?
Question 3
