The rationale of this experiment was to examine differences in the electrical conductivity, indicating salinity, and a redox potential between Aquanity and tap water. Using an accurate and calibrated electrical conductivity meter (El-Hamma model WTW3510), a conductivity test was conducted for each of the water types. The electrical conductivity of a chemical solution indicates the concentration of dissolved salts in the solution.Electrical conductivity is considered as indication of the total dissolved salts in a solution. The results in the following table clearly show that the highest electrical conductivity, among the water types, was found in the Aquanity water, with a mean value of 525-527μs/cm. This indicates a large concentration of dissolved salts in comparison to other water types.
Additionally, a redox test was conducted, indicating the transfer of electrons from one chemical type to another, causing a change in the level of oxidation state. During oxidation, one chemical type transfers an electron, thus raising its own oxidation state. During reduction, a chemical type receives an electron, thus is reducing its own oxidation state. According to the results, there were no meaningful differences found between the different water types (the value for different water types was close to 282 mU). Therefore, water redox reaction did not constitute a differentiating parameter among the water types.
