Hi I Wanted To Know How Evry1 Found The Paper Were There Any Questions That You Found Hard Or What Did You Think Was Good About It Jus General Discussion Really Thank U
The first quetion on u2. Electroltye one. I put Cryolite for Al and Steel + Titanium for Cl. What exactly is an electroltye
1ST QUESTION PART 1)BAUXITE ORE DISSOLVED IN MOLYEN CRYOLITE (BUT I ONLY PUT MOLTEN CRYOLITE) 2)NaCl must be aqeous. Electrolyte is the solution in which electrolysis can take place
CRap, 3 makrs lost there!
i put just cryolite for part 1 and brine for part 2. I should have put bauxite ore dissolved in molten cryolite as u said. Damnit! I better get an A for both units or i will probably kill myself.
I put (bauxite) Al2O3 for 1st and brine(NaCl) for 2nd. But why it's 3 marks? Maybe need cryolite in 1st one. I didn't notice the mark, I think 1 one for each
do any of you have any unit 2 papers and markschemes?
