Electrolytic cell voltage vs amperage graph

Click For Summary
SUMMARY

The discussion focuses on the relationship between voltage and amperage in electrolytic cells, specifically analyzing whether side products form at higher voltages. The participant has conducted experiments with a voltage range of 2.2V to 7.8V, achieving an R2 value of 0.9997, indicating a strong linear relationship. This suggests that increased voltage does not lead to the formation of additional reactions under the tested conditions. The conversation emphasizes the importance of detailing cell components, including the electrolyte solution and electrode composition, to validate findings.

Hello.

I have been running several experiments on an electrolytic cell, and I am trying to determine if side products are being formed at higher voltages. My thinking is that once the initial potential barrier is broken, and the resistance stabilizes, a volt vs amperage graph should be linear if it is the same product being made throughout. Once a new product is being made, a change in resistance (likely decrease, as new ions are added to the mix) would happen, and there would be either a jump, or a change in slope on the graph.

Is my thinking off base? I have a graph ranging from about 2.2V up to 7.8V, and I get an R2 value of 0.9997. Would this not be a very good indication that the increased voltage is not causing other reactions?
 
You will need to be more definitive about your cell components;i.e., electrolyte solution used or if using a melt system, composition of electrodes, power source as well as more detail on your plan of interest.
