Electrolysis of NaHCO3 solution with lead electrodes

Click For Summary
SUMMARY

The electrolysis of saturated sodium bicarbonate (NaHCO3) solution using lead electrodes results in the dissolution of lead electrodes, forming lead carbonate or basic lead carbonate, particularly at elevated temperatures. The Pb2+ ions generated at the anode react with hydroxide (OH-) and carbonate (CO32-) ions, leading to the formation of basic lead carbonate. This process is essential for producing lead (II/IV) oxide through the calcination of basic lead carbonate. Safety precautions are critical due to the toxicity of lead and its compounds, especially at high temperatures.

PREREQUISITES
  • Understanding of electrolysis principles
  • Knowledge of lead chemistry and its compounds
  • Familiarity with Pourbaix diagrams for lead
  • Safety protocols for handling toxic materials
NEXT STEPS
  • Research the electrolysis process of sodium bicarbonate solutions
  • Study the formation and properties of lead carbonate and basic lead carbonate
  • Examine the calcination process of basic lead carbonate to produce lead oxide
  • Learn about safety measures for working with toxic substances like lead
USEFUL FOR

Chemists, materials scientists, and anyone involved in electrochemical processes or lead compound synthesis will benefit from this discussion.

Hey.
If i carry out electrolysis of saturated sodium bicarbonate solution with lead electrodes, will the lead electrodes will dissolve to form lead carbonate (or basic lead carbonate if temperature is higher) or the lead ions will migrate from anode to cathode and deposite there?

I think that the Pb2+ ions will react with OH- and CO32- to form basic lead carbonate.
I want to do this so that i can make Pb (II/IV) oxide as calcination of bacis lead carbonate yields it.
Thanks in advance.

I would start by consulting Pourbaix diagram, however, dealing with lead and its compounds (especially in the high temperatures) is difficult, as lead is quite toxic. Do you have any experience or means to deal with it properly/safely?

Is lead carbonate stable on anode, or does it get oxidized further?
Lead sulphate is insoluble and insulating, yet it is oxidized at anode to lead dioxide. Does lead carbonate do the same?
