Titrations Terminology: 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) http://4.bp.blogspot.com/_QOi-X-GyYSE/SM1w7SfTjaI/AAAAAAAAAEQ/CBSOThGPF50/s320/titration.jpg

Titration Curves Shows the equivalence point of the titration You will be determining your equivalence point in this lab http://upload.wikimedia.org/wikipedia/commons/thumb/5/50/Titration_of_weak_acid_with_strong_base.PNG/400px-Titration_of_weak_acid_with_strong_base.PNG

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 http://en.wikipedia.org/wiki/Titration
