hahaha go ahead jay100 and vent all your frustrations!Ok, for the first question of this option topic, what did you think/say 'X' was?
Whats your reasoning? LOL, was so thrown offf by this
hopefully it will!! but I heard some options were hard as well so I don't know.Conc H2SO4
BTW will Industrial Chem scale well this year, considering how many people found it weird?
I think it's fair to say that most exams this year is hard... Well not necessarily hard but just different from what is expected. I think you needed to actually know the concept to answer the question. eg equilibrium and titration and all themThe worst question i have ever seen, my Chemistry teacher said they screwed up and that it was a hard test.
This is exactly, 100% correct. I just looked it up: http://www.finishing.com/173/41.shtml (and also cross-referenced)liquid x = conc. sulfuric acid
CuSO4.5H2O(s) <=> (write conc. H2SO4 where you'd write the catalyst) CuSO4(s) + 5H2O(l)
Hydrous CuSO4 is blue and conc. sulfuric acid acts as a dehydrating agent, turning the colour of the crystals from blue to white.
