Passing electricity through saline soln.

(1/1)

WazzaB:
Why does a salt solution turn yellow when an electrical current is passed through it using pieces of copper sheet?

gregpawin:
What kind of salt?

AWK:
I guess this is NaCl solution, and at the beginning of electrolysis solution of chlorine can show pale yellow-green colour.

Mitch:
Color may also be due to your electrodes eroding. What metal are you using?

jdurg:
I believe that in the first post he mentions copper sheets, so I believe that he is using a copper electrode.  If the electrodes were indeed corroding, the solution would take on a greenish color due to the aqueous copper ions and the chlorine.
