A back titration is similar to a direct titration, but a bit more difficult. When an end point is not easily identified due to no colour change, an excess volume of a reactant of KNOWN CONCENTRATION is added to the reactant of unknown concentration. Then the resulting mixture is titrated again (or titrated back) to find the volume of the unreacted reactant, which will tell us the amount that DID react with the solution of unknown concentration. You need to take into account the amount of excess reactant originally added. The relevant calculations can then be taken out.
Hence there are three reactants namely A,B,C. Such that it is to find the purity of C.
This titration is possible only if A and B can react with each other and A and C can react with each other but the product of A and C do not react with B.

What are complexometric titration method?
Direct titration, Indirect titration, back titration, replacement titration and so on
What is a back titration?
A back titration is a form of titraiton in which an excess of standard reagent is added and then the reverse of the titration is carried out.
What difference between titration and back titration?
In fact, a back titration is carried out as in a very similar method to an ordinary titration. the only difference is in the context. Consider an unknown acid solution. Then a known amount of excess alkali was added to the solution and made them react. Then the process of finding the amount left from the alkali is known as the back titration.
Why is phenolphthalein an appropiate indicator for back titration?
it's not in all cases. Only for titration of weak acids.
Explain the technique of back titration?
it is very good

When should back titration used instead of back titration?
when we do not know nothing about the other titrant.

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.
Does anyone know what back titration really is?
no lol
Is an alternative pH indicator practical for the back titration?
No.

How does back titration differ from a direct titration?
direct titration involves the direct and stepwise addition of a standard titrant to the analyte whilst the back titration involves reacting a standard excess titrant wth an analyte solution of an unknown concentration, then reacting the excess (left over) titrant with an analyte of known concentration to determine the concentration of excess titrant.
