![]() Zinc chloride is used as a source of chlorine at the air-conditioning plant for purifying water for final use. Zinc chloride can be used to remove zinc from the galvanizing bath by crystallization of ZnCl 2. ![]() It is also used as a blocking agent in the paint process. Zinc chloride is used as a galvanic anode in automobile batteries. Another optimization strategy uses zinc chloride to control alkali-silica reaction (ASR) in concrete mixtures with high fly ash content. This modification has a positive impact on strength development and early age properties. ![]() It has been successfully used as a concrete additive to remove carbon dioxide from cement mixture, which reduces its heat of hydration by 50%. It is also used for water line flushing and softening of water. Zinc chloride is used in the zinc industry, mainly for the purifying of sphalerite concentrates. Zinc chloride is a common ingredient in commercial bleach, and is also used on its own as an alternative to chlorine-based bleaches. These agents are preferred to others because they produce fewer yellow color shifts in the picture. In the dye fixing process, it is used as a developer of cyan and magenta dyes, although other developers are also used, such as ammonium bromide and zinc chloride sulfate. Zinc chloride is used as a photo-developing agent in photographic processes. ZnCl 2 melts at approximately 447 K, decomposes to Zn and Cl 2 at 167 K, and on heating above 151 K gives off a gas of ZnCl 3. ZnCl 2 crystals are octahedral with pairs of equivalent ZnCl- ions (each having six coordinate Cl- ions) joined together by ionic bonds. Zinc chloride has a melting point of 311 and decomposes to solid crystals at temperatures below 191, releasing hydrogen gas. It is the most common form in which zinc metal is produced commercially, but it also occurs in nature as the mineral sphalerite. What is molecular formula for zinc chloride? Zinc chloride is a chemical compound of zinc and chlorine.
