Learners observe that the melting of a solid and the freezing of its liquid occur at the same temperature. The melting point is an intrinsic property and is used to identify a substance.

In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.
Naming Binary Ionic Compounds Containing Variable Oxidation State Cations (Screencast)
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.
Naming Binary Ionic Compounds Containing Fixed Oxidation State Cations
Learners examine a table containing the names of common cations and anions. They then check their knowledge by answering a series of questions.
Determining Empirical and Molecular Formulas
Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
