Unit 1 – Day 6 Naming Acids

Acids Acids are ionic compounds where hydrogen is the positive ion. All acids must be dissolved in water to have acidic properties (corrosive, etc). They can bond with non-metals to make binary acids. They can bond with polyatomics to make oxy acids.

Binary Acids Binary acids involve bonding hydrogen ionically with a non-metal. They are named using a pattern. – Hydro______________ic acid Examples: HCl – Hydrochloric acid H 2 S – Hydrosulfuric acid

Oxy Acids Oxy acids involve bonding hydrogen ionically with a polyatomic ion. They are called oxy acids because the polyatomic ion contains oxygen. They are named using a pattern. – _____________________ic acid Examples: HClO 3 – Chloric Acid HNO 3 – Nitric Acid

Writing Formulas for Acids Acids are ionic, so the criss cross rule applies. Hydrogen always has a charge of +1. The negative ion’s charge must be looked up. Example: Sulfuric acid. H SO
