    Haha your up late :P How do you think you went in chem. overall?? Could i ask what school you go to? (or if your a selective school students atleast?)

    Industrial Chem ?!

    This is exactly, 100% correct. I just looked it up: http://www.finishing.com/173/41.shtml (and also cross-referenced) Thats not general knowledge, how did you know the whole equation + colour change??

    questions about industrial chemistry.

    LOL @ _deloso, anode half-equation produces H+ (Hydrogen ions)..... Hence, why the solution becomes acidic and litmus papers turns red. (Cathode also produces OH-) Farrout, your friend is F'd btw :P Scaling can't help him, with a raw mark that low!!

    questions about industrial chemistry.

    Yeahh my school didnt go through pracs. properly aswell. But i read about it somewhere. 0.1 mol/L was considered dilute, hence 0.05 mol/L is def. dilute. This prac. was meant to STRESS the importance of using BRINE (This is just CONC. NaCl) in Electrolytic cells; not just dilute NaCl

    questions about industrial chemistry.

    I did: Anode: 2H20 --> O2 (g) + 4H+ (aq) + 4e- [Used standard potential tables] Cathode: 2H20 + 2e- --> H2 (g) + 2OH- [Also on standard potential sheet] Looking at the products, this explains for the change of the litmus paper. Btw, Cl2 (g) bleaches litmus paper WHITE Since...

    I said 15 LOL . I think its C (you and nav. said it was A). Oswald process, i just talked about temp/pressure required for all of them.... related to equilibrium...then talked about activation energy, particicle colission theory and noted that VERY different exothermic conditions between the 1st...

    Industrial Chem ?!

    haha yeahh i found the option topic hard (even though, a few others found it relatively easy) And why is it conc. sulfuric acid?!?!?! Does it act as a dehydrating agent or something, thereby removing the colour of the crystals??
