Topic-1

Ionic and Molecular Solultions

Key Concepts

  1. Acids, bases and salts make ionic solution; and others make molecular solution. Ionic solutions produce ions in solution.

  2. Ionic solution conduct electricity, but molecular doesn’t. Ions in solution cause current to flow.

  3. Solubility is the maximum amount of solute that will dissolve in a volume of water.

  4. Unsaturated Solutions: The rate of dissolving > the rate of crystallizing

    Saturated Solutions: The rate of dissolving = the rate of crystallizing

    Supersaturated Solutions: The rate of dissolving < the rate of crystallizing

  5. Saturation exists when some undissolved material is present, and equilibrium exists between the dissolved and undissolved material.Molar solubility – moles / liter
