rate dissolve = rate crystallise
Semipermeable Membrane
Solutions & Colligative Properties
Dimensionless
A barrier that allows solvent molecules to pass while blocking larger solute particles.
Sol
Solutions & Colligative Properties
nm
A colloidal system consisting of solid particles dispersed throughout a liquid medium.
Solubility
Solutions & Colligative Properties
g/100 g
The maximum quantity of a solute that dissolves in a given amount of solvent at a specified temperature to give a saturated solution.
S = g solute / 100 g solvent
Solubility of Gases
Solutions & Colligative Properties
mol/L
The amount of a gas that dissolves in a given volume of liquid at a stated temperature and partial pressure.

Solute
Solutions & Colligative Properties
mol
The component of a solution present in the smaller amount, which is dispersed throughout the solvent.
Solution
Solutions & Colligative Properties
Dimensionless
A homogeneous mixture in which one or more substances are dispersed uniformly at the molecular or ionic level in another.
Solvation
Solutions & Colligative Properties
kJ/mol
The surrounding and stabilisation of a solute particle by a shell of solvent molecules.
Solvent
Solutions & Colligative Properties
L
