Complete the table using the thermometer values.
Mark the points for both potassium chlorate(V) and sodium chloride on the grid. Draw a smooth curve through the potassium chlorate(V) points and a straight line through the sodium chloride points. Extend each line in both directions so that, at the lower end, each one crosses the $y$-axis and, at the upper end, the lines cross.
Using your graphs, what mass of potassium chlorate(V) is dissolved in $10\text{ g}$ of water at $0\degree\text{C}$?
What mass of sodium chloride is dissolved in $10\text{ g}$ of water at $0\degree\text{C}$?
Using your graphs, determine the temperature at which the two salts have the same solubility.
Calculate the solubility of both potassium chlorate(V) and sodium chloride at the temperature you gave in (i).
The student has two boiling tubes: one contains $2.0\text{ g}$ of potassium chlorate(V) in $10\text{ g}$ of water, and the other contains $2.0\text{ g}$ of sodium chloride in $10.0\text{ g}$ of water. Both tubes are at $40\degree\text{C}$. The mixtures are stirred. Use your graphs to describe what is in each tube.
Using your graphs, compare how raising the temperature affects the solubility of each salt.
