TitrationsTerminology:• Titrant- Solution you are

adding to perform the titration• Analyte- solution you are

titrating into (usually of an unknown concentration)

• End point/ equivalence point- point at which the reaction is complete (you use the volume of titrant you added at the end point to calculate concentration of analyte)

Weak Acid/ Strong Base Titration

• We are doing this type of titration in our lab• Must use pH meter to detect end point• Rapid change in pH is indicative of your end

point
