Section 7.1 Naming and Writing Formulas for Acids and Bases Acids are… Compounds that give off hydrogen ions (H1+) when dissolved in water Will start the formula with H. There will always be some Hydrogen next to an anion. The anion determines the name.

F. Rules for Naming acids: (anions with different suffix: -ide, -ite, -ate) 1. If anion attached to hydrogen ends in -ide, put prefix hydro- and change -ide to -ic acid HCl - hydrogen ion and chloride ion = hydrochloric acid H2S hydrogen ion and sulfide ion = hydrosulfuric acid

F. Rules for Naming acids: * If the anion has oxygen in it, then it ends in -ate or –ite (polyatomic) change the suffix -ate to -ic acid (use no prefix) Example: HNO3 Hydrogen and nitrate ions = Nitric acid change the suffix -ite to -ous acid (use no prefix) Example: HNO2 Hydrogen and nitrite ions = Nitrous acid

F. Rules for Naming Acid hydro-___-ic acid ____-ide _____-ic acid Normal ending ____-ide ____-ate ____-ite Acid name is… hydro-___-ic acid _____-ic acid _____-ous acid

Practice by naming these: HF H2S H2SO3 H2SO4 HCN hydrofluoric acid hydrosulfuric acid sulfurous acid sulfuric acid hydrocyanic acid

Write formulas for these: hydroiodic acid carbonic acid phosphorous acid hydrobromic acid acetic acid HI H2CO3 H3PO3 HBr CH3COOH * breaks the rule of starting with H

Names and Formulas for Bases Base - an ionic compound that produces hydroxide ions (OH1-) when dissolved in water Bases are named the same way as other ionic compounds: The name of the cation (which is a metal) is followed by the name of the anion (which will be hydroxide).

G. Names and Formulas for Bases To write the formula: Write the symbol for the metal cation followed by the formula for the hydroxide ion (OH1-) then use the criss-cross method to balance the charges. NaOH is sodium hydroxide Ca(OH)2 is calcium hydroxide

Practice by writing the formula for the following: Magnesium hydroxide Iron (III) hydroxide Zinc hydroxide Mg(OH)2 Fe(OH)3 Zn(OH)2
