VCE chem question--role of electrolyte solution as compared with salt bridge (1 Viewer)

[azura1996]

Hey guys,

just a general question on why do salt bridge & electrolyte both "completes the circuit"? is it just because they balance the charge at each electrode?

So for instance, for the SO42-ions, it migrates to the anode(+) (and combines with any anions as a product of oxidation) but it does not take part in the recharging reactions?

I am able to identity species being oxidisied/reduced and do questions, but i thought it would be better to clarify on this issue too,

Thank heaps guys!!!!!

A salt bridge usually keeps both sides neutral, it allows the spectator ions to basically migrate.

Hey Adrita,
Thank you! actually i found this section of "purpose of salt bridge" and it is exactly what you said.
