By definition, that's wat an electrode is - a site where electrons are accepted. You guys surely learnt about inert electrodes...

hahaha You'll most likely get a mark above me ;)

It's my study room thats actually splendid. LOL I can barely walk in here without making foot contact with paper - I really need to get a shitload of garbage bags and just throw all this shat out.

Tonight at the marking centre there will be only senior markers looking at randomly-selected Chem papers to refine the marking guidelines/criteria, and start to look at determining raw band cut-offs.

If its Epstein-barr virus/Mononucleosis/Glandular fever, I've read on a BOS document that they don't accept that as illness/misadventure :( But then again, definitely submit an illness/misadventure appeal... they could be fair and offer u leeway.

LOL why me :shy:

Confuciousnesss over that stupid titration. If we used the wrong titre volume, then its 1 mark lost - big deal. lol

The exam supervisors said they are... and I was like "huhhhhhh"... what is there's crosses/corrections and shit.. Maybe they use some special optical character recognition software or something... who knows, who cares. LOL

ah fuck lol oh well, they'll take one mark off for using the wrong titre volume.

I got 1.057 mol/L for the [HCl], so did the rest of my class. Did you guys do the 1:2 mole ratio of Na2CO3:HCl thing? And then find the concentration of HCl, using the titre volume (23.45mL)

We'll i'd imagine that the salt bridge wouldn't allow that.

Well, I said that the Nickel Nitrate solution would become a darker green, as more Ni2+ would be formed, as the oxidation progressed, increasing the electrolyte concentration. And in the other half-cell, no colour change would occur, since the KCl solution is colourless, and the formation of...

Hopefully we will see each other in Pharm nxt year... :) enjoy ur break.. we'll chat again around the results time ;)

Exactly, thats a common trap people fall into. I agree in saying it's B.

Well, I think so. I've read somewhere on this forum, I think cem said that, that she's come across a script where the student has answered/approached the question from a very different angle etc. and then the senior marker decided it was an A-range response. So I think yeah, if your resonse is...

lol dittooo hardddddddd I just kept looking over the 4 D's questions.. and i'm like, i've obviously screwed up a question I don't realise.

I got 0.16mg of Zinc. Once you drew your graph with a line of best fit, you used the average absorbance, and then saw that 1.6mg/L was the average concentration. then, since the sample was 100mL in volume, you multiply the concentration by volume, to get the mass. 1.6mg/L x 0.100L = 0.16mg

By definition a cathode is the site where electrons are accepted. So the cathode is the Platinum, not the Chlorine. IMO anyway..
