1. K+ and Cl- ions go to the opposite ends of the salt bridge ( K+ near the oxidative part and Cl- near the reductive part). The other way round, K+ moves to the cathode
Sorry, it was silly of me.
2. The Zn 2+ ions move to the reductive half and the SO42- ions go to the oxidative part. This neutralizes the excess charge. I am not sure about SO42-, the concentration should be 1 mol L-1 in each half-cell so there shouldn't be any net movement
Ok. But it was given like that in Wikipedia right??
So, according to you, it's something like diffusion of ions due to difference in concentrations right? So, if we use ZnCl2 and CuSO4, concentration of SO4 is zero in the other half. So, will they start diffusing through the salt bridge till they become evenly distributed???
I guess that I am terribly wrong somewhere.
