What apparatus is used in titration?
A burette, a pipette and conical flask
What is the titration flask?
It is the conical flask in which the solution from the burette flows into and which you add the indicator into.
Do you use titrant in conical flask?
yes we use titrant in the conical flask ,this is because titrant is a solution we use in burrete for titration in this process we titrant the solution in the conical flask along with an indicator
Is there any difference between conical flask and titration lask?
I alsys used a conical flask without any graduations- pyrex for preference- less liable to break.
During titration why use a conical flask and not a beaker?
So you can swirl the contents around without spilling them. =]

Why do you use conical flask in the titration process rather than beaker?
It prevent the solution from spelling

Are conical flasks used for?
its used to put chemicals in or you can make the chemicals yourself!!!A glass laboratory flask of a conical profile with a narrow tubular neck and a flat bottom, used to manipulate solutions or to carry out titration.
Why is titration repeated without indicator?
In a titration the pipette is used to transfer 25 cm3 (usually to ±0.05 cm3) of a solution into a conical flask. Another solution that reacts with the solution in the conical flask is carefully added from a burette until it has all exactly reacted. This is called the end point of the titration (or equivalence point of the reaction). There needs to be a way of knowing when the end point is reached. An indicator may be needed. Often a titration is repeated until successive titres are within 0.1 cm3.
Why was the conical flask not washed with the alkali solution it was going to contain during titration?
So that no extra moles of NaOH were present in the flask.
Can a beaker be used instead of conical flask in titration?
no because the liquid may spill out and it is difficult to mix the contents in beaker by shaking the beaker
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.
What are possible sources of error in a conductrimetric titration experimentWhy is the solution placed in the burette very much more concentrated than that in the conical flask Explain graphs?
