Molar Mass Determination by Freezing Point Depression
Students determine the molar mass of an unknown fatty acid dissolved in a known fatty acid using freezing point depression and colligative properties. This lab replaces traditional experiments using hazardous organic solvents.
Solubility: Solutions
Solubility: Solutions
Students qualitatively and quantitatively describe the relationship between temperature and solubility for gases and solids. This lab uses two forms of magnesium (magnesium chloride and magnesium sulfate) to compare solubility of ionic solids and create a solubility curve.
