Chromium (Cr) Metal Safety & Health Precautions: a) Water insoluble chromium (III) compounds and chromium The general equation of this type of chemical reaction is. Active metal + acid salt + hydrogen gas. This is an example of a single displacement reaction. One element (the active metal) displaces another in a compound (the acid). Active metals displace the hydrogen from acids producing hydrogen gas. The two most common acids used are Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys.: p.1265 The coating serves as a corrosion inhibitor, as a primer to improve the adherence of paints and adhesives, as a decorative finish, or to preserve electrical conductivity.
