AS chemistry coursework.......HELP!!

AS chemistry coursework.......HELP!!
My lad's chem coursework is due in tomorrow, (yes, I know!!! )
Part of it is labelled "justification", and it's on the end of a write up about titration. The planner tells us that it enables the student to get the highest marks, but not what it means.
It urges the student to discuss it with the teacher, but of course, idiot boy hasn't.
Does anyone know what it means, and how he can access these marks?
Thanks in advance,
Alcazar

*Scratches head thinking back to A level chemistry*
Probably a bit hard to tell without more information... Maybe it's asking for justification of the method chosen, chemicals used, etc.

It could easily be either of the above 2 posts.
As said more info would help such as which exam board?
Have you tried Google, there seems to be a far bit of stuff about it on there.

From memory, and it's been years since i did my A Level, it's a laboratory technique by which you can determine the concentration of an unknown reagent using a standard concentration of another reagent that chemically reacts with the unknown.

It seems to be on hold. Business and family commitments have come into play.
We didn't go down too well in Australia for some reason...
It'll have to be restarted soon.

A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and therefore the precise quantity of reactant in the titration flask. A buret is used to deliver the second reactant to the flask and an indicator or pH Meter is used to detect the endpoint of the reaction.

the justification bit, is all about dicussing your results, (did the experiment go as planned? did you have to change things as you were going as they didnt conform to your original idea, do the results you came up with, follow the theory that you were testing? would you do anything different next time? could you improve it anyway) (thats all i can remember from my AS level chem course work for which funny enough i did a titration
