This site might help you re: titration experiment conclusion what questions could i answer and elaborate on in my acid-base titration lab conclusion.

Back titration is designed to resolve the problems encountered with forward titration back titration can be used for many reasons: when the analyte is volatile or insoluble in water when the analyte contains impurities that. The discussion: what do your results mean the discussion section of the lab report is where the results are interpreted, especially as they relate to the goals stated in the introduction. Back titration is a titration done in reverse instead of titrating the original sample, a known excess of standard reagent is added to the solution, and the excess is titrated a back titration is useful if the endpoint of the reverse titration is easier to identify than the endpoint of the normal titration, as with precipitation reactions.
