13. Bases
Most Bases are Ionic Compounds and therefore dissolve in water into ions
Ba(OH)2(s)  Ba2+(aq) + 2OH-(aq)
Since ions are formed in water, bases will conduct electricity
Base Name
Chemical Formula
Use
Sodium Hydroxide
NaOH(aq)
Making paper
Calcium Hydroxide
Ca(OH)2(aq)
Decreasing acidity in lakes and soil
