NH 4 OH ammonium hydroxide

Lesson Summary

• Acids are molecular compounds that dissolve in water to produce hydronium ions and an anion.

HA(aq)+H 2 O(l)→A−(aq)+H 3 O+(aq)

• The naming rules for acids are based on the suffix of the anion. Formulas for acids are written by balancing
  out the charge of the anion with the appropriate number of hydrogen ions.


• Bases are ionic compounds consisting of hydroxide ions and a cation. Naming and formula writing for bases
  follows the same guidelines as for other ionic compounds.
