You place 4.5 g KNO3 into a test tube containing 5.0 mL of H2O. The solid white powder rests at the bottom of the clear, colourless liquid. #1 Which substance is the solute? KNO3 or H2O? #2 Is this mixture a solution? Yes or No? You place this test tube into a hot water bath and the temperature rises. When the temperature reaches 55°C the powder dissolves and disappears from view. #3 Now, is this mixture a solution? Yes or No? #4 Is KNO3 ionic, polar covalent, or nonpolar covalent? Solubility is the largest amount of solute that can dissolve in exactly 100 grams of solvent. #5 Using your same initial test tube ratio of solute and solvent: How many grams of KNO3 could dissolve in 100 g H2O at 55°C? #6 Is this solution saturated or unsaturated 55°C?
