Titration Curve and Conductivity graphs of Strong Acid/Strong Base
- A titration curve is the plot of the pH of the analyte solution vs the volume of the titrant added for the neutralization reaction to occur.
- A titration curve provides an idea regarding the equivalence point of an acid-base reaction, which is the exact phase in which the amounts of acid and base will be just precise for the reaction to occur.
- The graph also represents the pH value in the equivalence point which varies depending on how strong or weak the acids and bases are.
- For strong acid-strong base titration, pH = 7 at equivalence point
- For weak acid-strong base titration, pH > 7 at equivalence point
- For strong acid-weak base titration, pH < 7 at equivalence point

- Let us suppose that our analyte is HCl (strong acid) and the titrant is NaOH (strong base). The following graph is obtained:
