1. Hydrated Compounds and Naming Acids

2. Hydrated compounds A hydrated compound is an ionic compound that contains water within its crystal structure This water can be driven off by heating the compound Ex. Copper(II) sulfate pentahydrate. CuSO 4 ·5H 2 O

3. Naming Acids An acid is an ionic compound, with Hydrogen as its cation, that has been dissolved in water (aq)

4. Naming Acids Binary Acids: The prefix “hydro” is used followed by the other element, ending in “ic” Examples: HCl hydrogen chloride hydrochloric acid H 2 S hydrogen sulphide hydrosulphuric acid HBr hydrogen bromide hydrobromic acid

5. Naming Acids Tertiary Acids (also called OXO acids)(H+ bonded to polyatomic ion) If the name of the anion ends in “ate”, the name of the acid ends in “ic” Example: H 3 PO 4 hydrogen phosphate phosphoric acid If the name of the anion ends in “ite”, the name of the acid ends in “ous” Example: HNO 2 hydrogen nitrite nitrous acid

6. Naming Acids Prefixes “per” and “hypo” Examples: HClO hydrogen hypochlorous hypochlorite acid HClO 4 hydrogen perchloric perchlorate acid
