  1. Solubility and the Particle Theory

  2. Remember….particle theory • Particles are in constant motion! • Particles are constantly rotating, vibrating, and moving about from one place to another.

  3. In a solution... • This means that solute particles are always bumping against other solute particles as well as solvent particles. https://www.youtube.com/watch?v=xdedxfhcpWo

  4. The quiet video... what the heck did you learn? • Dissolving a salt crystal (sodium chloride) begins with water particles bumping into salt particles at the edge of the crystal. • The water particles are attracted to the individual salt particles. • With constant motion, they are able to free individual salt particles from the larger crystal.

  5. A little more on the quiet video! • Individual salt particles are then carried away by bumping into water particles. • This leaves room for other water particles to bump into and carry off other salt particles at the edge of the crystal. • The process continues until all the salt particles are surrounded by water particles and evenly distributed throughout the water.
