Neutralization Recations

Neutralization Reaction: When an acid and base are mixed they will yield (produce) water and a salt (ionic compound). This is a type of double displacement reaction.

Acid + Base -> Salt + Water

Titrations

A titration is a procedure that allows us to determine the pH of an unknown solution by determining the concentration (in molarity) of an unknown acid or base. Watch the following video to view a titration: https://safeshare.tv/x/g8jdCWC10vQ.
Procedure:

1. A standard solution (the titrant: a solution with a known pH and concentration) is slowly added to the unknown.
2. An indicator is also added to the unknown solution. The indicator is a chemical that changes color in the presence of an acid or base.
3. When the color of the unknown solution changes due to a change in pH, we have exceeded the equivalence point. The equivalence point is the point at which the solution is neutral (Point where # moles of acid = # moles of base).
   

• The Equivalence Point is the point at which the moles of acid equal the moles of base
