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.

What are complexometric titration method?
Direct titration, Indirect titration, back titration, replacement titration and so on
What is over-titration?
over titration is when too much titrant is added to the analyte in a titration procedure.
When should back titration be used instead of direct titration?
when we do not know nothing about the other titrant.
When to use back-titration instead of direct titration?
When you have passed the tipping point and the color indicator turns from it's color to the clear color of the original solution. Then you back titrate to color again.
Why is a back titration sometimes used for an analysis rather than a direct titration?
Back titrations are used when a reaction occurring in the conical flask can not be detected using an indicator such as phenolphthalein. So, after this titration has been performed, the 'excess' is then titrated with something that can be detected more easily using phenolphthalein etc.

Define the analyte in a titration?
1) The analyte is the substance in a titration whose concentration is unknown.
What is 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.
Techniques used for determination of calcium and magnesium in natural water samples?
Atomic absorption spectroscopy, complexometry titration, colorimetric titration direct potentiometric titration by using of selective ion-electrodes.
Why is phenolphthalein an appropiate indicator for back titration?
it's not in all cases. Only for titration of weak acids.
