1. Acid and Base Ch 15 and 16 7-1

2. Naming of acids 1.In a binary acid, the negative anion ends in -ide. The name begins with the prefix hydro-, stem and ends with -ic acid. hydro______ ic acid HF HCl HBr hydroflouric acid hydrochloric acid Hydrobromic acid stem

3. 2. In an oxy acid, the negative anion ends in –ate, use the stem and the name ends with -ic acid. ______ ic acid HNO 3 H 2 SO 4 H 3 PO 4 CH 3 COOH nitric acid phosphoric acid sulfuric acid acetic acid

4. 3. In an oxy acid, if the negative anion ends in –ite, use the stem and the name ends with -ous acid. _______ ous acid HNO 2 H 2 SO 3 H 3 PO 3 nitrous acid sulfurous acid phosphorous acid
