Solubility and the Particle Theory

Solubility and the Particle Theory. Remember….particle theory. Particles are in constant motion! Particles are constantly rotating, vibrating, and moving about from one place to another. In a solution.

Presentation Transcript

  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.
