Potassium dichromate (K2Cr2O7) is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is potentially harmful to health and must be handled and disposed of appropriately. It is a crystalline ionic solid with a very bright, red-orange color. It is also known as potassium bichromate; bichromate of potash; dipotassium dichromate; dichromic acid, dipotassium salt; chromic acid, dipotassium salt; and lopezite.
Sodium Chromate can be prepared from chromite (Fe(CrO2)2) ore by treating sodium carbonate. Sodium chromate is hygroscopic. It absorbs moisture in air to give tetrahydrate. It is easily dissolves in water to give yellow chromate ions. Addition of a dilute acid will shift the above equation to the right and the solution turns from yellow to orange. However, addition of an alkaline solution will shift the equation to the left, turning the solution from orange to yellow. Between two extremes it is possible for both chromate and dichromate ions to coexist in proportion according to the value of the pH.
Zinc chrome comes in two types , type 1 and type 2 depending on the chrome content. Type 1 is of higher chrome content (42% approx) and is primarily used in marine paints and anti corrosive paints. Type 2 is of a lower zinc content (17 % ) and is used in inferior quality paints.
