The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte.
The end point is the point in a titration when a physical change occurring immediate after the equivalence point

What is the difference between the equivalence point and the end point in a titration process?
The equivalence point in a titration is when the amount of titrant added is stoichiometrically equivalent to the amount of analyte present. This is where the reaction is complete. The end point, on the other hand, is when the indicator changes color, signaling the completion of the titration. The end point may not always coincide exactly with the equivalence point.
What is the difference between end point titration and equivalence point?
Endpoint titration refers to the point in a titration where the indicator changes color, signaling that the reaction is complete. Equivalence point, on the other hand, is the point in the titration where the moles of the titrant are stoichiometrically equal to the moles of the analyte. The equivalence point does not necessarily coincide with the endpoint, as the indicator may change color before or after reaching the equivalence point.
What is the difference between the end point in a titration and the equivalence point?
Oh, dude, the end point in a titration is when the indicator changes color, indicating the reaction has almost reached completion. The equivalence point, on the other hand, is when the moles of acid equal the moles of base in a reaction. It's like the end point is the flashy showstopper, and the equivalence point is the behind-the-scenes workhorse.
Does The equivalence point and the end point of a titration occur at the same place in a titration?
The equivalence point and the end point of a titration do not always occur at the same place. The equivalence point is the point at which stoichiometrically equivalent amounts of reactants have been mixed, while the end point is when the indicator changes color. In ideal conditions, the end point would occur at the equivalence point, but this is not always the case due to factors like human error or issues with the indicator.
In a titration when does the indicator change color?
when the equivalence point of a titration is achieved.. Added: (More precisely:) The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
What is titration error?
Titration error is simply the difference between the end point of a titration and the equivalence point of it. It can mathematically defined as Error = Vol(End Point) - Vol(Equivalence Point)
How does the equivalence point of a titration differ from its end point?
The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change.
Which is the end point in acid base titration?
The end point in an acid-base titration is the point at which an indicator changes color and signifies that equivalence has been reached between the acid and base being titrated. This is when the amount of acid and base are in stoichiometric proportions.
What is the difference between end point and equilibrium point in chemistry?
In chemistry, an endpoint is the point in a titration where the indicator changes color, signaling that the reaction is complete. On the other hand, an equilibrium point is the point in a reaction where the concentrations of reactants and products remain constant over time, indicating that the forward and reverse reactions are occurring at the same rate.
What is the relationship of the successive equivalence point volumes in the titration of polyprotic acid?
the end point will be a simple multiple of the first
What is the relationship of the successive equivalence-point volumes in the titration of a polyprotic acid?
In the titration of a polyprotic acid, the successive equivalence-point volumes decrease because each equivalence point corresponds to the complete neutralization of one acidic proton. This leads to a decrease in the moles of acid present in the solution, requiring less titrant to reach the subsequent equivalence points.
What is the difference between equivalent point and end point in analytical chemistry?
The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte. The end point is the point in a titration when a physical change occurring immediate after the equivalence point
