Physical Properties of Calcium Chloride and Hydrates. Boiling Point Elevation In order for a liquid to boil, the vapor pressure needs to be at the same pressure as the atmospheric pressure above it.Example: What is the freezing point of water when 30.0 g of calcium chloride, CaCl2, is dissolved in 100. g of water? For example, dissociation of sodium chloride and calcium chloride in water can be represented by the following equations.Boiling-point elevation, freezing-point depres-sion, vapor-pressure lowering, and osmotic pressure are all colligative properties. The difference between the boiling points of the solution, and the pure solvent, is called elevation of boiling point of the solvent. i 3 for calcium chloride (CaCl2) in water, due to its full dissociation Ca2 and 2Cl- ions. In summary, the addition of a nonvolatile solute to a liquid causes both a boiling point elevation and a freezing point depression.A 1m solution of calcium chloride contains 3 mol of solute particles per 1 kg of water (1 mol of Ca2 and 2. Boiling point elevation.Materials and Setup: Two large demonstration beakers of boiling water on hot plates Two large demonstration beakers of ice/water mix Sodium chloride (NaCl) Calcium phosphate (Ca3 PO4)2 Four thermometers. Boiling point elevation depends on the identity of the solvent and the concentration of solute particles, but not the identity of the solute. Consequently, just like freezing point depression, boiling point elevation can be used to determine the molar mass of a solute. colligative property freezing-point depression boiling-point elevation. Reading Strategy.Inferring Why would calcium chloride (CaCl2) be a better salt for this purpose than sodium chloride (NaCl)? Section 16.3 Colligative Properties of Solutions 489.
