It's been a long long time, but I'm pretty sure that looks like the set up used for alcohol titration ... which at least at my school we did in teams for 4 or so. Did you not do this? If I did it, I'd assume that it's a standard part of the UK Curriculum (though again, that was some time ago).
A quick google appears to back me up to some degree?[1] (See "Student Activity 3")
