Hi guys..
I understand that an electron has electric field lines radiating inwards... do these lines eventually start at a positive charge ? or put another way, do the field lines of a positive charge terminate at a negative charge?
Do charged ions also have field lines radiating in/outwards ?
Suppose we have a container which is split into two by a partially permeable membrane, that allows only positive ions (A+) to pass through it. Say we fill one half of the container with a solution that contains both positive cations A+ and negative anions B- .
Naturally, the A+ ions will diffuse across the membrane to the other side of the container (assuming the ions are in an aqueous solution).
If the ions also have field lines and contribute to an electric field between A+ and B- , wouldn't there exist an electric field starting at one side of the container ( where the A+ ions diffused into ) and terminating at the B- ions ? and wouldn't this electric field oppose the motion due to diffusion ? And since an increase in diffused A+ ions will cause an increase in the electric field strength opposing the motion, wouldn't that mean that there will be no diffusion at all taking place ?
Thanks guys..
