Introduction to Solutions

Author: carolyn fruin

Learning Targets:

  • I can define solute, solvent and solution.
  • I can define the term solvation and describe the different processes that ionic and molecular compounds go through in this process.
  • I know the difference between dispersion and dissociation and ionization.
  • I can define saturated and unsaturated and quantitatively compare two solutions.
  • I know the difference between an electrolyte and nonelectrolyte.

Basic Introduction to Solutions

This is a quick introduction to some of the terminology for the solution unit. Vocabulary is really important in this content area due to some very subtle differences in word definitions. Pay special attention to understanding the words and how they are used.

PhET Lab Simulation - Sugar and Salt Solutions

Load the Sugar and Salt Simulation. This activity will help learners visualize solution processes and properties.

Possible Learning Goals

  • Use pictures and proportional reasoning to explain changes in concentration
  • Draw what happens at the molecular level when compounds dissolve in water
  • Identify if a compound is a salt or sugar by macroscopic observations or microscopic representations.
  • Explain how using combinations of solutes changes solution characteristics or not.
  • Use observations to explain ways concentration of a solute can change.
  • Describe ways the formula, macroscopic observations, or microscopic representations of a compound indicates if the bonding is ionic or covalent.
