Zn + 2 HCl → ZnCl2 + H2 Hydrated forms and aqueous solutions may be readily prepared by treating pieces of Zn metal with concentrated hydrochloric acid. Example: Determine molarity of 37.2% hydrochloric acid. The solutions, based on zinc chloride, help in the formation of resinate, linoleate and zinc laurate. ZnCl 2 itself is hygroscopic and even deliquescent.Samples should therefore be protected from sources of moisture, including the water vapor present in ambient air. Zinc chlorides, of which at nine crystalline forms are known, are colorless or white and highly soluble in water. Refer to the Technical Support-Reference Documents on our website.
