Purpose
The majority of chemical processes are reactions that occur in solution. Important industrial processes
often utilize solution chemistry. "Life" is the sum of a series of complex processes occurring in solution.
Air, tap water, beverages, and household ammonia are common examples of solutions.
A solution is a homogenous mixture of substances with variable composition. The substance present in
the major proportion is called the solvent, whereas the substance present in the minor proportion is
called the solute. It is possible to have solutions composed of several solutes. The process of a solute
dissolving in a solute is called dissolution.
In this topic, we will learn about the basic properties of solutions, how to prepare standard solutions
and how to use stoichiometry in solution chemistry. We will also learn what affects solubility including
temperature, pressure, and the nature of the solute and solvent.

By the end of these Topics, you should be able to demonstrate proficiency in the following areas:
Essential Understandings
The concepts developed in this standard include the following:
 Molarity = moles of solute/L of solution.
 [ ] refers to molar concentration.
 When solutions are diluted, the moles of solute present initially remain.
 The saturation of a solution is dependent on the amount of solute present in the solution.
 Solutions can be a variety of solute/solvent combinations: gas/gas, gas/liquid, liquid/liquid,
solid/liquid, gas/solid, liquid/solid, or solid/solid.
 Polar substances dissolve ionic or polar substances; nonpolar substances dissolve nonpolar
substances. The number of solute particles changes the freezing point and boiling point of a pure
substance.
 A liquid’s boiling point and freezing point are affected by changes in atmospheric pressure.
 A liquid’s boiling point and freezing point are affected by the presence of certain solutes.
Knowledge, and Skills
In order to meet this standard, it is expected that students will:
 perform stoichiometric calculations involving the following relationships:
-
mole-mole
mass-mass
mole-mass
mass-volume
mole-volume;
volume-volume
 perform calculations involving the molarity of a solution, including dilutions.
 interpret solubility curves.
 examine the polarity of various solutes and solvents in solution formation.
