You are provided with a beaker, a thermometer, a stirrer Stopwatch/clock, measuring cylinder, table salt, water, and other necessary materials. i. You Measure 200cm\(^{3}\) of water into the beaker. ii. Heat the water until it boils steadily for about 2 minutes. iii. Read and record the boiling point \(b_0\). iv. Add table salt of mass M = 10.0 g to the boiling water and stir continuously until another boiling point \(b_1\) is attained. v. Read and record \(b_i\). vi. Evaluate \(\theta_{i}\) = (\(b_i\) - \(b_0\)) vii. Using the same mixture, repeat the procedure four more times by adding 10.0 g of salt each time to give the cumulative mass \(M_i\) of salt as 20 g, 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 b. ix. Tabulate your readings. x. Plot a graph with \(M_i\) on the vertical axis and \(\theta_{1}\) on the horizontal axis. xi. Determine the slope, s, of the graph. xii. State two precautions taken to ensure accurate results. (b) i. Define the boiling point of a liquid. ii. What effects do impurities have on the boiling point of a liquid?
