    Hi!

    Could someone explain to me how you know whether to put the alkali or acid in the burette? + Go through why we titrate things?

    Thanks!

    We titrate to find out the concentration of an unknown solution using a solution of konwn concentration.

    It does not really matter which you put in the burette, but alkalis tend to be corrosive to glassware particularly if not rinsed out well. The burette tap can get gunged up by residual alkali, so we try to put acids in rather than bases.

    Thank you! + Is the substance with unknown concentration usually in the conical flask or burette? Or does that not matter either? (:

    It does not matter - it rather depends on operational issues, such as ease of observation of colour change etc.
