Based on the titration curve, the titration is of a strong acid strong base and pH at equivalence point is 7.
What is equivalence point?
The equivalence point in an acid-base titration is the point at which equal amount of acid and base have reacted.
The equivalence point in a strong acid-strong base titration is at pH 7.
In a weak acid-strong base titration, the pH is greater than 7 at the equivalence point.
In a weak base-strong acid titration, the pH is less than 7 at the equivalence point.
From the titration curve;
- volume of base was needed to neutralize the acid is 50 mL
- pH at the equivalence point is 7
- the number of moles of hydronium ions and hydroxide ions at the equivalence point are equal.
Therefore, the titration curve is of a strong acid strong base.
