At this point in the titration curve, we are in a buffering region, and the curve will be relatively flat. 3 ... 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.
