1) Acids are compounds that produce hydrogen ions (H+) when dissolved in water and contain hydrogen. The name of the acid is determined by the anion to which the hydrogen is bonded. 2) If the anion ends in "-ide", the prefix is "hydro-" and the suffix is changed to "-ic acid". If it contains oxygen, the suffix is "-ate" for "-ic acid" or "-ite" for "-ous acid". 3) To write formulas for acids, hydrogen comes first followed by the anion. The charges must balance. For names, the prefix and suffix indicate if oxygen or hydrogen is present in the anion.

1. Acids Writing names and Formulas

2. Acids Compounds that give off hydrogen ions when dissolved in water. Must have H in them. H will always be next to an anion. The anion determines the name.

3. Naming acids If the anion attached to hydrogen ends in -ide, put the prefix hydro- and change -ide to -ic acid HCl -> hydrogen ion and chloride ion Hydrochloric acid H 2 S -> hydrogen ion and sulfide ion Hydrosulfuric acid

4. Naming Acids If the anion has oxygen in it it ends in -ate or -ite change the suffix -ate to -ic acid HNO 3 -> Hydrogen and nitr ate ions Nitr ic acid change the suffix -ite to -ous acid HNO 2 -> Hydrogen and nitr ite ions Nitr ous acid

5. Name these HF H 3 P H 2 SO 4 H 2 SO 3 HCN H 2 CrO 4 Hydrofluoric Acid Hydrophosphoric Acid Sulfuric Acid Sulfurous Acid Hydrocyanic Acid* Chromic Acid

6. Writing Formulas Hydrogen will always be first The name will tell you the anion Make the charges cancel out. Starts with hydro- no oxygen, -ide No hydro, -ate comes from -ic , -ite comes from -ous

7. Write formulas for these hydroiodic acid acetic acid carbonic acid phosphorous acid hydrobromic acid HI HC 2 H 3 O 2 H 2 CO 3 H 3 PO 3 HBr

8. Bases Writing names and Formulas

9. Bases Ionic compounds that produces hydroxide ions (OH - ) when dissolved in water. Must have OH in them. OH will always be next to a cation. Name bases like other ionic compounds Name of cation followed by name of anion

10. Writing Formulas Cation will always be first Followed by the correct number of OH - ions Make the charges cancel out. Example: Aluminum Hydroxide Al +3 and OH - Al(OH) 3

11. Write the name or formula Lithium Hydroxide Mg(OH) 2 Lead (II) Hydroxide Sn(OH) 4 Zn(OH) 2 LiOH Magnesium hydroxide Pb(OH) 2 Stannic hyrdroxide Zinc hydroxide
