Salt Bridge

[jowrose]

Ok, I've been doing some electrolysis but I cannot figure out how to make a salt bridge to keep the reactions separate. I've tried using yarn wet with the solution, but that didn't work. So I tried using thin strips of paper towel, and that failed as well. So then I took a piece of tubing and siphoned it so that it was full of solvent, and again I was left with no reaction. What am I doing wrong?

when you run electricity through a conductor, the longer and more narrow it is, the greater the resistance created.

it doesn`t sound like you`ve done anything wrong if it`s made a complete circuit, but you may just have to crank up the voltage a little to overcome this resistance.

Ah ok. thanks yt.
