Electrolysis: Show the dependence of current on the concentration of sodium chloride (salt) in the electrolyte.

Science Fair Project Information
Subject: Chemistry
Grade level: Middle School - Grades 7-9
Academic Level: Advanced
Project Type: Experimental
Cost: Medium
Awards: First Place, Canada Wide Virtual Science Fair (2006)
Affiliation: Canada Wide Virtual Science Fair
Year: 2006
Description: When an electrical current passes through a solution of sodium chloride electrolysis occurs. The dependence of current vs. the concentration of sodium chloride in the salty water (electrolyte) was experimentaly tested. The experimental results were explained using the mathematical form of Faraday’s laws of Electrolysis.
