# Ch 9: Overview of Chemical Solutions

This chapter teaches your middle schooler about chemical solutions, solubility, dilution and chemical reactions. The short video lessons can easily keep students' attention, and parents and teachers can check student progress with lesson quizzes and a chapter exam.

## Overview of Chemical Solutions - Chapter Summary

These engaging and informative video lessons expand on and/or reinforce in-class lessons your middle school student has received. Lessons describe the basic principles of various aspects of chemical solutions from simple processes, like mixing and dilution, to more complex concepts, such as colligative properties and molarity. The lessons also teach the necessary mathematical tools to accompany these studies. Check your student's understanding of the material with short quizzes that accompany each lesson, and use the chapter exam to gauge retention and synthesis of chemical solutions concepts.

## Chapter Lessons and Objectives

Lesson Objective
Polar Molecule: Definition and Examples Students will learn how to identify polar and non-polar molecules by analyzing the bonds between their constituent atoms.
Solutions, Electrolytes and Nonelectrolytes Instructors teach basic principles of solutions and the properties of both ionic solutes (electrolytes) and non-ionic solutes (non-electrolytes).
Solubility and Solubility Curves In this lesson, students are taught how much of a given solvent can be dissolved in a given solution (solubility) and the relationship of solubility to temperature.
Dissolved Gas: Process and Examples Students are presented information on how gases dissolve along with examples from the natural environment to support the concepts.
Dissolving Liquids: Process and Examples Instructors provide information on the dissolution of liquids and examples of the process from real life.
Calculating Molarity and Molality Concentration Students learn to calculate molar concentration in solutions by determining the number of moles per liter of solution or per kilogram of solvent.
Calculating Dilution of Solutions This lesson helps students learn to calculate dilution using the law of conservation of mass along with the given molarity and volume of the component solutions.
Colligative Properties and Raoult's Law Instruction presented in this lesson discusses the properties of solutions which rely on molarity and how vapor pressure and the mole fraction of solvents relate to the vapor pressure of a solution.
Using Colligative Properties to Determine Molar Mass Students learn to calculate the mass of molecules within a solution through boiling point elevation and freezing point depression.
Facts about Water Molecules: Structure, Properties & Quiz Instructors present information regarding water molecules, the properties of which are crucial to understand in the study of chemistry.
Dissociation Constant and Autoionization of Water With this lesson, students learn about the dissociative properties of various complexes and molecules, including how two water molecules can share protons and dissociate into a base and acid.
Using Chemical Reactions to Identify Substances Students learn to use the chemical and solvent properties of various substances to identify unknown substances using known solutions.
