May I ask why electrons won’t move if there’s a build up of charge?

Hi Audrey, They will be attracted/repelled by the half cell charges and therefore not move across the wire. Thanks!

What is the mobility of the K and Cl ions inside the bridge? Can the bridge be so slow to create a charge imbalance , at least in the initial transient when the external circuit is closed on the load? What I am curious about is if there can be a temporary violation of Kirchhoff's current law due to accumulation and rarefaction of charge at the bridge extremities. (Left side releases K ions near the left end, right side releases ions near the right end, but no net current can be measured by a clamp ammeter in the middle of the bridge. Only when the charge imbalance passes a certain threshold the electric field causes a drift current in the mid section - has this ever been observed?)

Hi Copernicofelinis, excellent question. Honestly, I do not know. At the general chemistry level we assume it is instantaneous and a non-issue. In real life, I do not have an answer. I suggest you ask your professor for their thoughts as well. Thank you for the great question!

@@OldSchoolChemistry considering how many years have passed since I last talked to my chem prof, it is safe to assume I would need a seance to ask him the question. And since he was a stubborn atheist, he would probably not answer even if he could. I would do the experiment myself, but nowadays it's easier to buy a semiautomatic rifle than a chemistry set... I think I would need three to five cells to give a strong enough (near short circuit) current to be read by a clamp ammeter on the middle salt bridge. And it would probably need to be a current probe attached to an oscilloscope because the transient could be just a few tens of microseconds... It would be epic seeing KCl breaking KCL, tho. Anyway, thanks for taking the time to reply, and kudos for your tutorials: they are a joy to watch. I love your enthusiasm.

Ions don’t discharge at the ends of the salt bridge right?

Hi Ahyes1, I am afraid I do not understand your question. Ions in the salt bridge do move into the solution to maintain a neutral charge in the solution. I hope that helps. Thanks!

1:17 what’s the purpose of the salt bridge and the only thing that is moving is the salt and not the ions?
@OldSchoolChemistry

Hi Annie, The purpose of the salt bridge is to keep the half cells a neutral charge. As the ions/metals exchange in each half reaction they change the charge of the half cell. The salt bridge ions move to maintain a net zero charge in each half cell. I hope that helps. Thanks!

No, because the product is soluble. The cations and anions will exist in the water solution as separate ions.
