Chapter 3.4

Solutions and Molarity: Picturing What Is Dissolved

A teaspoon of salt in a glass of water and the same teaspoon in a swimming pool are both salt water, and no one would confuse them. Concentration is the number that keeps them apart.

in preparation · lesson 12 of 45

By the end

  1. 01Distinguish homogeneous from heterogeneous mixtures at the particle level
  2. 02Compute molarity, solute amount, or solution volume from the other two
  3. 03Draw a particulate diagram of a solution that shows concentration and interactions
  4. 04Read relative concentrations and solute–solvent interactions off a particulate diagram
