Hydrated Compoundsand Naming Acids
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.• CuSO4·5H2O
Naming Acids
• An acid is an ionic compound, with Hydrogen as its cation, that has been dissolved in water (aq)
Naming Acids
Binary Acids:• The prefix “hydro” is used followed by the other
element, ending in “ic”
Examples:HCl hydrogen chloride hydrochloric acidH2S hydrogen sulphide hydrosulphuric acid
HBr hydrogen bromide hydrobromic acid
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:H3PO4 hydrogen phosphate phosphoric acid• If the name of the anion ends in “ite”, the name of the
acid ends in “ous”Example:HNO2 hydrogen nitrite nitrous acid
Naming Acids
Prefixes “per” and “hypo”
• Examples:HClO hydrogen hypochlorous hypochlorite acid
HClO4 hydrogen perchloric
perchlorate acid
