So I was doing electrolysis on two silver electrodes and sodium thiosulfate. Some observations
The voltage drops extremely fast from 2 V to less than 1 V in 15 minutes, possibly because of the thiosulfate reduction.
Gases are liberated out of solution.
The solution turns black quickly.
Alert: I am using a fume hood.
Since I'm afraid of this spoiled eggs smell I just want to know if I am in any way creating hydrogen sulfide? Just want to be sure that the gas is tetrathionate and not hydrogen sulfide.
My other concern is with the voltage. How can I keep it from dropping so fast?
