Nickel Chloride Formula

Nickel Chloride contains no water and hence is an anhydrous chemical compound. They are yellow-brown colour crystalline of an inorganic compound. The other names of nickel chloride are nickelous chloride, nickel(II) salt of hydrochloric acid. It is a toxic chemical that acts as an irritant when it comes in contact with mucous membranes, skin, and eyes. It is a carcinogen that is known to cause life-threatening disease like lung and nasal cancers. Let us know the chemical composition of Nickel chloride.
