Calcium Chloride - TETRA Chemicals
With our proprietary manufacturing process and high quality raw materials, we produce the highest quality calcium chloride products available in North America. By using food grade quality hydrochloric acid and high purity limestone as raw materials, we are able to deliver calcium chloride with very low levels of alkali metals, iron, and other impurities.
Bleach And Zinc Reaction
During the reaction zinc metal gives two electrons to two iodine atoms to produce zinc +2 ions and iodide -1 ions. Vinegar and bleach have been tried and seem to affect the rusting rate. I suspect a larger dose of bleach might have been more effective, and I am still experimenting with this technique.
