- What is the difference between the equivalence point of a titration and the end point of a titration?
- They are not different.
- The equivalence point is when the reaction has reached completion while the end point is an estimate of the completion.
- The equivalence point is when the reaction has reached completion while the end point is the half-way point of the titration.
- The equivalence point allows us to calculate unknown quantities of reactants while the end point does not.
Homework Answers
b) The equivalence point is when the reaction has reached completion while the end point is an estimate of the completion.
d) The equivalence point allows us to calculate unknown quantities of reactants while the end point does not.
