2. Water will always pass an electric current and support these reactions. Adding a soluble ionic compound, a salt such as sodium chloride, greatly enhances the extent of reaction, however, since it allows more current to flow. In this case, the cations / anions, react at the electrode in preference to water. With this in mind, explain why a loss of color occurred at one electrode during the electrolysis of sodium chloride.
