WebThere are a number of differences between the titration curves for a strong acid versus the weak acid. Weak Acid Titration The weak-acid solution has a higher initial pH. The pH rises more rapidly at the start, but less rapidly near the end point. The pH at the equivalence point does not equal 7.00 (pH > 7.00) for the weak acid titration. PURPOSE WebA titration curveis a graphical representation of the pH of a solution during a titration Titration curves can be used to track the reaction of acids and bases and at the equivalence point, the amount of titrant added to neutralize the analyte can be recorded. This varies for different types of acids and bases due to their relative strength. WebAt the very beginning of the curve, the pH starts by falling quite quickly as the acid is added, but the curve very soon gets less steep.
