aqueous ammonia. The alkali formed by the reaction of sodium with water is sodium hydroxide. One of the most fascinating chemical experiments is the reaction between silver nitrate and copper wire in water. Formation of the solid is the driving force for this reaction - the quick explanation is that the forces attracting silver and chloride ions together are stronger than the solvation forces between those ions and water, as well as the forces holding them to sodium and nitrate ions. The silver is undergoing reduction; therefore, the silver electrode is the cathode. One day of lead time is required for this project. To be added to this model: Copper Nitrate flowing into solution and forming a complex with three water molecules turning the solution blue. After sitting for awhile, the white will settle to the bottom. When silver nitrates runs out before the copper atoms, then we might have two (or multiples of two) gray copper agents, which really should correspond to one Cu atom that didn't finish undergoing a full oxidation to Cu+2.
