Which of the following statements is true for a salt bridge with the following redox reaction, right? So here we're talking about what side would my bromide ions flow. C contains neutral atoms that interact with the ions in both half cell compartments. We know that the salt bridge itself doesn't contain atoms which are neutral, it deals with neutral ions. So this is not correct. It's not atoms, it's ions, it's sodium ions flow to the magnesium cell half cell.

All right. So we know that the negatively charged ones like bromide ions would flow towards the add on compartment and the positive ones, in this case sodium ions would flow to the Catholic compartment. Remember the anode is where oxidation occurs and the cathode is where reduction occurs. Here, if we take a look at our overall redox reaction, we have magnesium going from zero to +2, so it's oxidation number increased. So it's being oxidized, which means it is the anode. OK, so this will be the magnesium compartment, or half some.

Cadmium goes from +2 to 0, so its oxidation number reduces. Therefore, it's the cathode. So we have our cathode compartment being the compartment being the captive. So if we look here, it's bromide ions will flow with the magnesium half cells. So bromide is in fact, yes, it should flow to the magnesium side because the magnesium compartment represents our anode. So this is true.

It wouldn't flow to the cadmium half cell because that's where reduction occurs. It's sodium ions flow. It should flow to the magnesium half cell. No, sodium should be flowing towards the cathode side which deals with the cadmium half some. So out of all our options, only A is correct.
