... 10. Electrolysis is used as a source of elements from their ions. Ex. Na from Molten NaCl, Cl2 from a NaCl solution. 11. 0.1663 A current is needed. 12. First 2.47 Volts should be 2.47 Amperes. That gives 4.100g of Fe deposited. 13. Corrosion is the loss of metals to a solution of some form. The pro ...

Water splitting
Water splitting is the general term for a chemical reaction in which water is separated into oxygen and hydrogen. Efficient and economical water splitting would be a key technology component of a hydrogen economy. Various techniques for water splitting have been issued in water splitting patents in the United States. In photosynthesis, water splitting donates electrons to power the electron transport chain in photosystem II.
