All right, so we have an electrochemical cell, and this question asks us specifically about the salt bridge.
00:05
So that's the thing containing the strong electrolyte, in this case, potassium nitrate, and what is it doing? so the reason for a salt bridge is if you, well, i actually don't know the direction of the flow.
00:23
So we'll just assume that this is the anode and this is the cathode, just for the sake of illustration.
00:32
So the point of the salt bridge is the anode is going to receive.
00:38
Anions, so the nitrate anions.
00:41
And the cathode is going to receive cations.
00:43
They're named conveniently so that you can keep track of that.
00:46
And that's to prevent the buildup of charge.
00:49
So there's tends to be a buildup of positive charge in the anode as oxidation happens.
00:53
And then the negative ions from the salt bridge will mitigate that.
00:58
And conversely, in the cathode, there tends to be a buildup of negative charge.
01:02
So you send positive ions in to mitigate that.
01:04
There's no electrons flowing out of the salt bridge.
01:07
The strong electrolyte and ions are flowing...
