1. Electrolysis Jarod Coulter

2. An electrolytic cell uses electrical energy to produce a change Electrolysis is forcing a current through a cell to produce a chemical change for which the cell potential is negative

3. Uses Charging batteries Chrome plating Producing certain metals Breaking apart water

5. 1 ampere = 1 coulomb of charge a second Using this information some stoichiometry can be done

6. Sample Problems

7. Water (the exception to everything) Needs a salt to be added for electrolysis due to so few ions in the water (hard for a current to pass through) It takes more voltage to oxidize water, this is called overvoltage. It is hard to say where it comes from, some difficulties transferring electrons, scientists think.
