.jpg) Ferric hydroxide can be wrote in Fe(OH)3 or Fe2O3.3H2O. It is unstable, which means its molecular formula is not constant. Therefore it is expressed in Fe2O3.3H2Ousually.
Our Ferric hydroxide product is dark brown fine particle. It is soluble in acid, insoluble in water, alcohol and ether. It is used as absorbent and for pharmaceutical production.
