For regenerating the consumed solutions, an electrolysis cell is used. This cell has anode and cathode compartments that are divided by permeable membranes. The anode compartment is fed the used chromic acid solution, and the cathode compartment is filled with sulfuric acid.
How do electrolytic cells work?
A non-spontaneous redox reaction is facilitated by an electrochemical device known as an electrolytic cell, which employs electrical energy. For the electrolysis of some substances, electrolytic cells are electrochemical cells. For instance, water can be electrolyzed (using an electrolytic cell) to produce gaseous oxygen and gaseous hydrogen. This is accomplished by lowering the non-spontaneous redox reaction's activation energy barrier by the flow of electrons (into the reaction environment).
The following are the three essential parts of electrolytic cells:
- Cathode (which is negatively charged for electrolytic cells)
- Anode (which is positively charged for electrolytic cells)
- Electrolyte
The cathode and anode exchange electrons through a medium that is provided by the electrolyte. In electrolytic cells, molten sodium chloride and water with dissolved ions are two common electrolytes.
