Main Introduction Initial Observation and Hypothesis Materials and Equipment Experiment Discussion Applications Conclusions

CONCLUSIONS

1. When the electrical current passes through the solution of sodium chloride electrolysis occurs.

2. We experimentally observed that the current through the salt/water solutions increased with the concentration of salt.

3. The experimental results were explained using Faraday’s Laws of Electrolysis.

4. Using the experimental results we developed a simple device to determine an existence or the concentration of salt in the water.

5. Our hypothesis agreed with the experimental results.
