Answer 2

B right?

Answer 3

no, that would be a metal wire directly connecting the electrodes.

What is in the salt bridge?

Answer 4

salt?

Answer 5

so positive and negative ions, these migrate towards the electrodes to compensate for the electrical charge build up.

Answer 6

so A?

Answer 7

Just incase you don't know what a salt bridge, it's a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell, a type of electrochemical cell. It maintains electrical neutrality within the internal circuit, PREVENTING the cell rapidly running its reaction to equilibrium.

Answer 8

right, so the answer is A?
