Acid-Base Reactions
Definitions
Strong Acids
HCl
HBr
HI
HNO3
HClO4
H2SO4
 Acid: a species that supplies H+ ions to
water
 Strong acid: an acid that completely ionizes
in water forming an H+ ion and an anion
 Weak acid: an acid that only partially
ionizes in water to give an H+ ion and an
anion
Definitions
Strong Bases
LiOH
NaOH
KOH
Ca(OH)2
Sr(OH)2
Ba(OH)2
 Base: a species that supplies OH- ions to
water
 Strong Base: a base that completely ionizes
in water forming a OH- ion and a cation
 Weak base: a base that is only partially
dissociated to form OH- ions in water
 Weak bases react with water and the OHcomes from the water. The remaining H+
ion form the water attaches itself to the
weak base.
Writing Equations for Acid-Base Reactions
Write the net ionic equation between citric acid, H3C6H5O7 and sodium
hydroxide.
General form: HB + OH- B- + H2O
H3C6H5O7 + OH-  H2C6H5O7- + H2O
Write the net ionic equation for phenylaniline, C6H5NH2 and hydroiodic acid.
C6H5NH2 + H+  C6H5NH3+
Write the net ionic equation for potassium hydroxide and perchloric acid.
OH- + H+  H2O
Write the net ionic equation for barium hydroxide and ascorbic acid, HC6H7O6.
OH- + HC6H7O6 -- H2O + C6H7O6-
