hey i have 1994 too!
can u tell me the page no. or the session no. please?i rote adding ions makes the water conduct more easily
..i read it in the buk dat adding impurities to water makes it conduct..i wrote that too. is it correct? i wrote better conductivityi rote adding ions makes the water conduct more easily
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 !!!!!!!!!!!!!!!!!!!!!!
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 carefully
they asked what electrode will be oxidized
just for your knowledge rust is a redox reaction

EXACTLY !!!!
did u look at sacrificial protection? this is kinda like that....the cathode iron is being sacrificed to protect the iron at anode even though it is in the bubbles, they are there just to confuse the student....how many marks was that question? just in case I am wrong lol....
