Titre, titration and titrate specific meaning

So the solution of known concentration is meant to be in the burette and unknown concentration in the conical flask.
Is the solution of known concentration in the burette called the titre or only when they are delivered into the conical flask, the volume is known as the titre?

Is the word titration used to describe the overall process of determining the concentration of a unknown solution by adding a base to an acid? Or just the process of adding a base to an acid and determining the end point?

There are several ways questions are worded for volumetric analysis such as _______ is titrated against ________ AND _________ is titrated with ________. I don't know if there are other ways they can phrase these questions but I came into these 2 types and am wondering how to identify the titre and aliquot?

I dont think it makes a difference as long as there is enough information to determine the amount of mole in one of the solution which reacts with the other. Like u could have the known in the conical flask and add the unknown (from the burette) until the equivalence point is reached and hence work out the amount of mole needed to react with your fixed known solution.

The volume of the solution delivered from the burrete is called the titre.

Tiration is a type of volumetric analysis and it doesn't matter which u add to which. you can add the base to the acid or the acid to the base. The only thing that will change if they are reversed is the titration curves. But the equivalence point will remain the same.
 and lastly the ____ before 'is titrated' or 'is titrated' means that is the substance in the burette. As far as i can see.

Aliquot is the known solution with concentraton and volume in the pipette...
it is the put into the conical flask
the unknown or the one you are trying to find is the titre... the solution in the burette...

Thanks for that.

So the solution that is used in burette is the titre or only when it is delivered to the conical flask (very specific volume)?

Is it always that when X titrated with or against, X is the titre? Or perhaps they can phrase it in such a way that the meaning is reversed?

usually when they say something titrated against something ... is saying the the amount of titre going into the conical flask... neutralising the aliquot... therefore we can get the volume of the titre .
well... in titration questions... find the compound that has the volume and concentration given .
that would usually be your aliquot
hope it helps ...

aliquot is always the pipette
titre is always in burette

HELP ME GRADUATE!
If you know anyone pregnant let me know :)

'titre' is the volume delivered by the burette.

and don't forget you can have redox titrations as well as acid-base.

It's not necessary that the Aliquot is the 'known'.  You will find this out if you do back titration pracs...
