Yep I said Alkali is in the beaker because we already know the amount? So i though you'd use the burette to drip the acid in until it neutralises the 25.0cm3 of alkali.
My prediction on grade boundaries:
i thought that c7 test was kinda bad but some of it went okay
for the ammonia question, my mind went completely blank so i just put that organisms take it in to survive, would i get a mark for that?
also why did the two people add sulfuric acid to their experiment?
i've got a further mathematics exam tomorrow too :?
