Neutralization Recations
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:
Procedure:
- A standard solution (the titrant: a solution with a known pH and concentration) is slowly added to the unknown.
- 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.
- 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
Titration Calculations
Steps to take when determining the concentration of an acid:
- Find moles of base.
- Find moles of acid.
- Find concentration of acid.
- Find moles of acid.
- Find moles of base.
- Find concentration of base.
