Section 11: Ionic Compounds
Ionic Bonding, Compound Formulas, Formula Prediction, Polyatomic Ions,
Naming Ionic Compounds, Hydrates, Lattice Energy
Ionic compounds are used everyday. They can be found in our foods, blood, and many of the electronic devices that are used on a daily basis. What are those compounds made of? What makes them categorized as ionic compounds? Throughout this section we will not only look at how these types of compounds are formed, but how to predict the formulas of different combinations of metals and nonmetals. It is important to understand that not all ions are composed of simply one atom. The picture here contains several of the more common polyatomic ions. This will be an important list for you to know, it is a vocabulary list just like in any other class. There will be references to these througdhout the rest of the year.

UsesAs a food additive that people use for flavor. It is one of the few minerals on the planet that people can ingest.
The reason why sea water has such a strong taste. It is used as a deicer in the winter. May be back titrated to assess the concentration of ethanol on an individual's breath (breathalyzer). It is also used in concrete mixtures and to stain different types of wood. Classic baking soda, has the ability to put out grease fires and emits carbon dioxide when heated or when reacted with simple household acids (vinegar or lemon juice). Used as an oxidizer in fireworks, meaning that it supplies the oxygen when fireworks burn and the light display is not dependent on outside oxygen. A nice blue colored ionic compound that is used as a herbicide, pesticide, and fungicide. |
