so is it substitution or photochemical?
I think both are accepted I put substitution....

so is it substitution or photochemical?
oh thank you. finally somebody answered me i wrote substitution as wellI think both are accepted I put substitution....
because nobody was answering so i got sadWhy so sad?!?!
hey i have 1994 too! can u tell me the page no. or the session no. please?Its electrode A............almost same question repeated in 1994 paper..........................I know guys u would ask for the paper but.....................the thing is having problem to being uploaded...................I tried editing it but it brings error........................First one was Zinc and second one Vanadium...............read on oxidation on net if u want the evidence.................................
i rote adding ions makes the water conduct more easily ..i read it in the buk dat adding impurities to water makes it conduct..wattttttttttttttttt..................ions r catalysts ..................................it was asking to SUGGEST only !!!!!!!!!!!!!!!!!!!!!
i wrote that too. is it correct? i wrote better conductivityi rote adding ions makes the water conduct more easily ..i read it in the buk dat adding impurities to water makes it conduct..
oh lol..is it correct..cux im rlly unsure of itu r the first person who has wrte tht ans.........me too.......i dont noe wht everyone is sayin !!!!!!!!!!!!!!!!!!!!!!
the too asked about which electrode RUSTS........according to that...........oxygen bubbles at A so """" A is the one that RUSTS """"Ppl why do u think its A?! Just give me the reasoning not just because some past paper said so and its link I cannot provide/ I dont remember which one etc.....
I think its B because the electrons were flowing from B to A and since Iron in electrode B was losing electons the iron was going into the solution as Fe(III) ions so the B would become smaller not A......it is giving the electrons to A to keep it from going into the solution as ions.....
So its B if u have reasoning for why its A do post as a reply....
Thx
haha maybe you shouldve read the question carefullythe too asked about which electrode RUSTS........according to that...........oxygen bubbles at A so """" A is the one that RUSTS """"

Aziz come at http://www.xtremepapers.com/communi...r-61-and-chemistry-paper-31-discussion.17091/ tell others frm our class to come here too !!!!!!!!! discussing physics tooo.................fast!!!!!!!!!!!!!!!i am sure i am gonna get almost 58-60 ! wish that is enogh to get an A*!
