VIII. Base Equilibria
Just as with acids, strong bases react with water to produce 100% products while weak bases do not.
For weak bases, the reaction always produces hydroxide ions and the conjugate acid of the base.
Exercise
Write Kb (hydrolysis) reactions for the following bases. Use the proper type of arrow in your
reaction.
+
C₂H302 (aq) H₂0 (4) = +1₂ H302 (98) +0H (42)
LiOH(s) + H₂0 (1) 1) (uptotical) +H ₂0
LiOH (S)
F-(aq)
Exercise 11
Calculate the pH of the following solutions of strong bases.
a) 3.7 x 10-4M KOH SB de
it to
Licu
+
