so supposing a conical flask/burette has recently been used for titration and is washed out with acid/alkali, what steps are carried out before the flask/burette can be reused?

wash it with distilled water then with acid/alkali!

what's the logic behind that?

no. I think you r saying wrong.
Whatever is the solution in the Burette than wash with with that stuff.

Reduce Error in collection. Like noting down the Values from the burette

what reading? pH?
all we want to do is neutralise the flask/burette

this is only for Accurate apparatus ..... when u wash it with distilled water it will leave some drops of water on the wall , by washing with the same stuff which is inside ur burrette so it will reduce error!

this contradicts everything.
First of all, the flask contained the alkali, but at neutralisation, there would be a slight excess of acid, right?
Secondly, is tap water acidic or alkaline?
Thirdly, any one in his right mind would of course use a dry flask instead of a wet one, containing no drops of water?
Fourthly, this experiment was initially carried out without having known the accurate values for titration.
