Solution
A homogeneous mixture of two or more substances in a single phase
Particles are thoroughly mixed and remains mixed indefinitely
Components of a solution
Solvent: does the dissolving; the larger amount
Solute: is being dissolved; the smaller amount

15. Electrolytes & Nonelectrolytes
Electrolyte – a substance that dissolves in water to give a solution that conducts electric current
Ionic compounds and highly polar molecules form electrolytes
Nonelectrolytes – a substance that dissolves in water to give a solution that does not conduct electricity
