Acids
Objectives: name acids and write formulas for acids
•
Define Acid-
Compounds that have hydrogen as the Cation
Skill #1: Naming Binary Acids
Define Binary Acid-
H and an element with a neg. valence #

Prefix hydro

Root of anion

Suffix ic
acid
Example: HCl
hydrochloric acid
Example: H2S hydrosulfuric
acid
Example: H3P hydrophosphoric
Example: HBr
acid
hydrobromic acid

Skill #2: Naming Ternary Acids
Define Ternary Acid- H
is combined with a polyatomic ion

Name the
anion

“ate” converts to ic

“ite” converts to ous
Example: H2SO4 sulfuric
acid
acid
acid
Example: HClO hypochlorous
acid
Example: HC2H3O2 acetic
acid
Example: H2CO3 carbonic

Skill #3: Writing Formulas for ALL Acids (Criss-Cross)

The Hydrogen is written

The Anion is written

The charges are crossed

The signs on charges are dropped
Example: Hydroiodic Acid
Example: Sulfurous Acid
first
second
over and written as a subscript for the other ion
