Remove the sodium metal from the container, allowing the excess oil to fall back into the jar. Cut the sodium to approximately the appropriate size while there is still a small amount of oil remaining on the metal. You will notice that shortly after the metal is cut, it turns from a bright metallic color to a dull white color.
Loss of sodium hypochlorite strength means more product will be needed when the bleach is used as a disinfectant. Sodium hypochlorite decomposition rate is dependent on the total ionic strength of the product, temperature of the solution, pH, and transition metal content of the solution.
