Graph titled "Solubilities of Salts." The horizontal axis reads Temperature given in Celsius. The vertical axis reads Solubility. There are three lines on the graph. The blue line represents sodium nitrate. The red line represents potassium nitrate. The green line represents sodium chloride. The graph depicts that sodium nitrate has a gradual increase of temperature with a increase in solubility; potassium nitrate has a dramatic increase in temperature and a dramatic increase in solubility; and sodium chloride hard a very slight incline on the chart relative to temperature and solubility.
