Acid Base Neutralization

Neutralization of acid + base proceeds to the product side, no llbm

Generally:  acid + base --> salt + water

A few examples:
Strong acid/Strong base
   HNO3(aq)  +  NaOH(aq)  -->  NaNO3(aq)  + H2O

Weak acid/Strong base:
   HC2H3O2(aq)  +  NaOH(aq)  -->  NaC2H3O2(aq)  + H2O

Strong acid/Weak base:
-difficult to see "salt + water" products; write strong acid as H3O+
HNO3 + NH3 becomes H3O+  +  NH3  -->  NH4+  +  H2O

And now for something a little amusing. On the first day of school, the Kindergarten teacher said, "If anyone has to go to the bathroom, hold up two fingers." A little voice from the back of the room asked, "How will that help
