WebbTwo key markers in a titration curve help us identify whether the analyte and titrant in a titration is a strong or weak, acid or base. The first marker is if the initial pH is above or below 7. If the pH is above 7, the analyte is either a weak or strong base. If the pH is below 7, the analyte is either a weak or strong acid.

WebbExperiment 17: Potentiometric Titration Objective: In this experiment, you will use a pH meter to follow the course of acid-base titrations.
