Electrolysis Jarod Coulter

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

Uses Charging batteries Chrome plating Producing certain metals Breaking apart water

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

Sample Problems

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.
