It is a common laboratory chemical, frequently used as an oxidizing agent. Despite its widespread use, potassium dichromate is highly toxic and carcinogenic.<br /> <br /> ==Chemical properties==<br /> Potassium dichromate is a bright orange crystalline solid. It is highly corrosive and a strong oxidizing agent. The compound is soluble in water and its solutions have a characteristic orange color.<br /> <br /> ==Production==<br /> Potassium dichromate is produced industrially by roasting [[chromite]] ore with [[potassium hydroxide]], followed by a reaction with [[oxygen]].<br /> <br /> ==Uses==<br /> Potassium dichromate has a wide range of uses. It is used in laboratories as an oxidizing agent, and in the field of [[photography]] for hardening emulsions and toning prints. It is also used in [[leather tanning]], as a [[wood stain]], and in the production of [[safety matches]].<br /> <br /> ==Health effects==<br /> Exposure to potassium dichromate can cause severe health effects. It is a known carcinogen and can cause skin and eye irritation, respiratory problems, and damage to the liver and kidneys. It is also harmful if swallowed.<br /> <br /> ==Regulation==<br /> Due to its toxicity, the use of potassium dichromate is heavily regulated. In the [[European Union]], it is classified as a Category 1B Reproductive Toxin, and its use in many applications is restricted by the [[REACH Regulation]].<br /> <br /> ==See also==<br /> * [[Chromium]]<br /> * [[Potassium permanganate]]<br /> * [[Oxidizing agent]]<br /> <br /> [[Category:Inorganic compounds]]<br /> [[Category:Oxidizing agents]]<br /> [[Category:Potassium compounds]]<br /> [[Category:Chromium compounds]]<br /> {{Chem-stub}}</div> Prab
