I am trying to do membrane electrolysis of sodium bicarbonate by using a salt bridge which is a paper towel soaked in electrolyte and one end dipped in bicarbonate solution, the other dipped in plain water. Using carbon electrodes, one in each solution and 12v DC 3A, I switch on the power but nothing happens.
The goal is to form sodium hydroxide, but no electrolysis occurs. I tried to test the system on two containers with salt solution bridged by a membrane. A small amount of bubbling happens.
So I think maybe resistance is too high through the membrane? Or that plain water is just too weak an electrolyte?
