8. Acid Demonstration All the reactions involve acids and we will be studying many reactions that involve acids. Therefore, you should know how to name and write the formulas of acids.

9. Naming and Writing Formulas for Acids and Bases How are they named?

10. Naming and Writing Formulas for Acids and Bases Some ants can give painful stings when threatened or disturbed. Certain ant species called formicines have poison glands that produce venom containing formic acid. You will learn the names and formulas of some important acids such as formic acid.

11. An acid is a compound that contains one or more hydrogen atoms and produces hydrogen ions (H + ) when dissolved in water. Acids have various uses. Naming Acids

12. Three rules can help you name an acid with the general formula H n X. When the name of the anion (X) ends in -ide, the acid name begins with the prefix hydro-. The stem of the anion has the suffix -ic and is followed by the word acid. Naming Acids

13. When the anion name ends in -ite, the acid name is the stem of the anion with the suffix - ous, followed by the word acid. 9.4

14. When the anion name ends in -ate, the acid name is the stem of the anion with the suffix - ic followed by the word acid. 9.4 Naming Acids

15. A Summary of the Three Rules for Naming Acids. Naming Acids

16. Use the rules for writing the names of acids in reverse to write the formulas for acids. What is the formula for hydrobromic acid? Following Rule 1, hydrobromic acid (hydro- prefix and -ic suffix) must be a combination of hydrogen ion (H + ) and bromide ion (Br – ). The formula of hydrobromic acid is HBr. Writing Formulas for Acids

18. Bases are named in the same way as other ionic compounds—the name of the cation is followed by the name of the anion. For example, aluminum hydroxide consists of the aluminum cation (Al 3+ ) and the hydroxide anion (OH – ). The formula for aluminum hydroxide is Al(OH) 3. Names and Formulas for Bases
