Define Colligative Properties of A Dilute Solution?
The colligative properties of a solution are usually considered to be:
1. Freezing-point depression: the decrease in the freezing point of the solution, com- pared to pure solvent at the same pressure.
2. Boiling-point elevation: the increase in the boiling point of a solution containing nonvolatile solutes, compared to pure solvent at the same pressure.
Electron occupies the available orbital singly before pairing in any one orbital occurs, it is : (1) Pauli's exclusion principle (2) Hund's Rule (3) Heisenberg's principle
