i wrote change in mass/ time taken and yes ratios shud be in whole numbers. but i want to ask u a question did it ask for state symbols in ionic formula? and do i get it wrong if i wrote 2Ag++2Cl-=2AgCl, multipled all by 2 for some reason :/
i don't remember the question, but i wrote:
Ag+ + cl-=Agcl

Here is what the question said....
The electrolye was like Fe(III) something......

The electrodes were of iron, and there was a pipe of oxygen at the anode.....
I put B and I was sure, but now Im confused....coz oxidation is loss of electons and the electrons are being lost at the cathode in this situation.....but its anode that is oxidised when its like a metal and like a non metal, here they are both metals(Iron) so oxidation could occur at both electrodes, and since the flow is from B to A it should be B....
this is a cell, and the more reactive metal is the anode.
oxidation always occurs at the anode
