Naming Acids and Bases

Naming Acids and Bases � Acids: ◦ a compound that contains one or more hydrogen atoms and produces hydrogen ions (H+). � Bases: ◦ An ionic compound that produced a hydroxide ion (OH-) when dissolved in water.

Naming Acids � Three Rules: ◦ 1) When the name if an the anion end in –ide, the acid name begins with hydro-. The end of the name has the suffix –ic and is following by the word acid. ◦ Example: HCl �The anion is chloride goes to chloric �Begins with hydro-. Goes to hydrochloric �Followed by the word acid. Goes to hydrochloric acid. �HCl is hydrochloric acid.

Naming Acids � 2) When the anion name ends in –ite, the acid name will end in –ous, followed by the word acid. ◦ Example: H 2 SO 3 �The anion is sulfite (SO 3) �The anion sulfite goes to sulfurous �Followed by the word acid. Sulfurous acid �H 2 SO 3 is sulfurous acid.

Naming Acids � 3) When the anion name ends in –ate, the acid name changes the suffix to –ic, and it is followed by the word acid. ◦ Example: HNO 3 �The anion is nitrate. �The anion nitrate goes to nitric �Followed by the word acid. Nitric acid. �HNO 3 is nitric acid.

Naming Bases � Bases are named in the same way as other ionic compounds– the name of the CATION is following by the name of the ANION. ◦ Example: Na. OH is sodium hydroxide

Practice � Give the names of these acids: ◦ HNO 2 ◦ H 2 S ◦ H 2 Cr. O 4 ◦ Give the names of these bases: �Li. OH �Mg(OH)2 �Pb(OH)2 �Al(OH)3

Practice Answers � Give the names of these acids: ◦ HNO 2 ◦ H 2 S ◦ H 2 Cr. O 4 Nitrous Acid Hydrosulfuric Acid Chromic Acid ◦ Give the names of these bases: �Li. OH �Mg(OH)2 �Pb(OH)2 �Al(OH)3

Assignment � Work �Q & A with Mrs. Branum � Ask � If on study guide as a test review and you shall receive! you do not work on study guide or ask questions, I WILL give you work to do. I have another assignment ready.
