Presentation Transcript

  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

  4. 1 ampere = 1 coulomb of charge a second • Using this information some stoichiometry can be done

  5. Sample Problems

  6. 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.
