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.
