Module 4 Intro

Module 4—Properties of Solutions

Lesson Summary

In this lesson you explored the following essential questions:

• How can the concentration of solute in a solution be expressed?
  
  
• How do you calculate amount concentration and determine the concentrations of chemical species produced by dissociation?
  
  
• How are solutions prepared in a lab?

Your study in this lesson has expanded your knowledge of solution chemistry and has enabled you to prepare and dilute solutions of a desired concentration. In solution chemistry, many questions must be solved mathematically; and you now have an understanding of how formulas can be applied to predict the concentration of dissociated ions in a solution.

Lesson Glossary

amount concentration: the proportion of solute (in moles) to volume of solution

stock solution: a concentrated solution that is used in the preparation of more dilute solutions of the same solute
