What is the relationship of the successive equivalence-point volumes in the titration of a polyprotic acid?
the end point will be a simple multiple of the first
What is the chemical process for back titration?
The chemical process for back titration is to titrate the analyte past the original end point/equivalence point, and then BACK titrate the excess titrant to equivalence.
Why does the pH change rapidly at the equivalence point of a titration?
The equivalence point represents a region where the amount of acid to base (or base to acid) concentration is equal. Before the equivalence point there is a greater amount of acid (or base, depending on the titration). After the titration there is a greater amount of base (or acid). This reverse in dominance results in a dramatic change in pH.
If the equivalence point of a titration is 5 what range of pH should the indicator be?
The indicator should change color right at the equivalence point, so 5.
What is the point in a titration at which the added solute reacts completely with the solute present in the solution?
It is the equivalence point.
What is the relationship of the successive equivalence-point volumes in the titration of a polyprotic acid?
the end point will be a simple multiple of the first
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)
What is the chemical process for back titration?
The chemical process for back titration is to titrate the analyte past the original end point/equivalence point, and then BACK titrate the excess titrant to equivalence.
What is the difference between the end point and the equivalence point?
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
Why does the pH change rapidly at the equivalence point of a titration?
The equivalence point represents a region where the amount of acid to base (or base to acid) concentration is equal. Before the equivalence point there is a greater amount of acid (or base, depending on the titration). After the titration there is a greater amount of base (or acid). This reverse in dominance results in a dramatic change in pH.
Where is the buffer region in a titration curve for the titration of a weak acid with a strong base?
It is the nearly horizontal region before the equivalence point.
What is the difference between the end point in a titration and the equivalence point?
These terms are synonyms.
What is the purpose of a titration?
The purpose of a titration is to find the equivalence point (stoichiometric point) of a solution. At the equivalence point, the moles of the titrant and analyte are equal to one another. At the midpoint of the solution, the pKa value is equal to the pH value.
What is endpoint in titration?
The endpoint of a titration is when the indicator first changes in appearance, or when an instrument first gives a reading which indicates that the titration is finished. The endpoint is always slightly after the equivalence point.
A titration of an acid and base to the equivalence point results in a noticeably acidic solution It is likely this titration involves?
a strong acid and a weak base.
Is Titration is a process of reacting an acid with a base until an equivalence point is reached?
Yes
How do you detect the equivalence point in acidic medium?
By titration (manual or electrochemical) with a base and an indicator.
