Monday: Finally Ms. K is here.
the topic for the day is about Acid and Base Dissociation Constant.
Acid Dissociation Constant:
- strong acids/base dissociate completely :. do not establish equilibrium
- if Ka > 1 = strong acid
- weak acids/base - establish equilibrium
- The equilibrium law: Ka= [H3O+][A-] / [HA]
-the Ka reflects the equilibrium that exists for as acid

Kb=[B+][OH-] / [BOH]

-the larger the Ka/Kb, the stronger the acid/base.
-the smaller the Ka/Kb, the weaker the acid/base.

that's about it.

note: June 1, due date of research project
