Properties of Acids
•All acids start with H (e.g. HCl, H2SO4)
•2 acid types exist: binary acids and oxyacids
•Each have different naming rules.

Naming AcidsBinary Acids:• Contain “H” and one other element• Depends on the state of the acid
To Name aqueous: (prefix) hydro- “nonmetal name” (suffix) –ic acid
HCl (aq) hydrochloric acidH2S (aq) hydrosulfuric acid
To Name non-aqueous (solid or gas): Hydrogen “nonmetal” – change the ending to -ide
HCl (g) hydrogen chlorideH2S (g) hydrogen sulfide

Naming Oxyacids• Contain “H”, “O” and one more element• Naming does not depend on the state (aq)
Steps 1) name the polyatomic ion
2) replace -ate with ic, -ite with ous3) change non-metal root for easier pronunciation4) add “acid” to the name
E.g. H2SO3
1) sulphite,
2) sulphous,
3) sulphurous,
4) sulphurous acid

Naming Bases
To name:
“metal” + “hydroxide”
Ex: NaOH = Sodium Hydroxide
KOH = Potassium Hydroxide
• Bases contain an OH group• C6H12O6 does not have an OH group• If an OH group is present it will be clearly
indicated: e.g. NaOH, Ca(OH)2 • Also notice that bases have a metal (or positive
ion such as NH4+ at their beginning)

• Some compounds contain H2O in their struc-ture. These compounds are called hydrates.
• This is different from (aq) because the H2O is part of the molecule (not just surrounding it).
• The H2O can usually be removed if heated.• A dot separates water: e.g. CuSO4•5H2O is
copper(II) sulfate pentahydrate.• A greek prefix indicates the # of H2O groups.
