Understanding Electrolysis of Sodium Formate
The Basics of Electrolysis
Electrolysis involves using an electric current to induce a chemical reaction that would not occur spontaneously. In the case of sodium formate (NaCHO2), the process decomposes the compound into useful products through the application of an electric current.
The Electrolytic Process
- Electrolyte: Aqueous solution of sodium formate.
- Electrodes: Typically, a platinum or graphite anode and a copper or graphite cathode.
- Power Supply: Direct current (DC) to drive the reaction.
Chemical Reactions
- Anode (Oxidation):
[ \text{HCOO}^- \rightarrow \text{CO}_2 + \text{H}^+ + e^- ] - Cathode (Reduction):
[ 2\text{H}_2\text{O} + 2e^- \rightarrow \text{H}_2 + 2\text{OH}^- ] - Overall Reaction:
[ \text{HCOONa} \rightarrow \text{CO}_2 + \text{H}_2 + \text{NaOH} ]
