Acid Nomenclature
Binary acid – contains two elements
H & a higher electronegative element
Table on page 468
Begin the name with “Hydro” then the name of the second element then “-ic” suffix

8. Chapter 14 Section 1 Properties of Acids-Bases p. 466-477
Acid Nomenclature
Oxyacid – contains hydrogen, oxygen and a third element, usually a nonmetal
Table on page 469
Name is based on the polyatomic ion
-ic more oxygen (-ate)
-ous less oxygen (-ite)

18. Arrhenius Acid & Bases HCl (g) + H2O (l)  H3O+ (aq) + Cl- (aq)
Arrhenius Acid - A chemical compound that increases the concentration of hydrogen ion, H+, in aqueous solutions
HCl (g) + H2O (l)  H3O+ (aq) + Cl- (aq)
H+ is equivalent to H3O+
Aqueous acids and bases are electrolytes.
Chapter 14 Section 1 Properties of Acids-Bases p

19. Proton, Hydrogen ion, Hydronium
H+ = a proton
H+ (or a proton), attached to a water molecule = H3O+ + - +
“+” means the atom has lost one electron
Chapter 14 Section 1 Properties of Acids-Bases p

20. Arrhenius Acid & Bases NaOH (s)  Na+ (aq) + OH- (aq)
Arrhenius Bases - A substance that increases the concentration of hydroxide, OH- in aqueous solutions
NaOH (s)  Na+ (aq) + OH- (aq)
NH3 (aq) + H2O (l)  NH4+ (aq) + OH-(aq)
Aqueous acids and bases are electrolytes.

Weak Acids
An acid that releases few hydrogen ions in aqueous solution. - Dissociates slightly
A reversible reaction in equilibrium
Organic Acids

24. Weak Acids Acid Ionization Constant Ka
CH3COOH(aq) + H2O(l)  CH3COO-(aq) + H3O+(aq)
[CH3COO-] [H3O+]
Ka = Keq =
[CH3COOH]
MORE dissociated  MORE products  HIGHER Ka  STRONGER acid
LESS dissociated  FEWER products  LOWER Ka  WEAKER acid

Strong and Weak Bases
Strong Bases – bases that dissociate completely – strong electrolytes
Formed from Group I & II metals
Weak Bases – bases that dissociate slightly – weak electrolytes
Example: Ammonia, NH3
NH3 + H2O  NH4+ + OH-
