Colligative Properties Colligative Property – a property that depends only on the amount of dissolved solute rather than on the chemical identity of the solute. Vapor pressure of a solution is lower Boiling point of a solution is higher Freezing point of a solution is lower Osmosis

Examples Vapor pressure – a nonvolatile solute lowers the vapor pressure of a volatile solvent. Freezing point – when a nonvolatile solute is dissolved in a solvent the freezing point is lowered. (salt in ice) Boiling Point - when a nonvolatile solute is dissolved in a solvent the boiling point is

Unformatted text preview: increased. (salt in water) Molality molality, m = moles of solute kilograms of solvent m = T / K or T = K m where K is a constant (equation for nonionizing solute) T = i K m ( i is the number of different ions) Procedure Notes Check your calculation for #1 with me before proceeding. Add the salt slowly to the water or your solution will boil over and you will have to start over. Your graphs should take up a whole page. It should have a title and both axes should be labeled. Show all your work and include units!...
