At a low pH, the coination of hydronium ion, H + and chloride, Cl-, ions will cause a very rapid corrosion. During storage, the pH of calcium chloride should always be kept at pH above 6.5. If a low pH is suspected, it should be measured, and a suitable base, i.e., NaOH or Ca(OH) 2 , should be added to increase the pH.
