1. Electrolysis of Salt Water Peter Lindner Ridgewood High School January 31, 2011

2. Today’s Setup

4. My tests VoltageCurrentH2H2 Two dead 9Volts7V27mAOKAY Cell Phone Charger5.1V23mAOKAY Power Supply34V168mAGREAT

5. Electrolyte Any substance containing free ions that make the substance electrically conductive Examples: Sodium Chloride Calcium Chloride Citric Acid Gatorade/Juices

6. Questions What are electrolytes? Why is the electrolyte solution needed? What is made at the Cathode? What is made at the Anode? What are the benefits of this setup? When compared to the PEM electrolyzer? What are the disadvantages?

7. REACTIONS Anode (positive): Cathode (negative): OVERALL: 2H 2 O  O 2 +4H + +4e - 4H + +4e -  2H 2 2H 2 O  O 2 +2H 2
