1. Names and Formulas of Acids and Bases Ch. 15-1 p. 542-549 Ch. 15-2 p. 550-558 Ch. 15-1 p. 542-549 Ch. 15-2 p. 550-558

2. Names and Formulas of Acids n HCl (g) named hydrogen chloride n HCl (aq) is named as an acid n Name focuses on the anion present

3. Names and Formulas of Acids 1. When anion ends with -ide, the acid starts with hydro-, and the stem of the anion has the suffix -ic followed by the word acid 2. When anion ends with -ite, the anion has the suffix -ous, then acid 3. When anion ends with -ate, the anion suffix is -ic and then acid
