demirIII
DemirIII is the Turkish term for iron in its +3 oxidation state, usually written as iron(III) or Fe3+. In chemistry, demir(III) denotes Fe3+ cations that form a variety of compounds and play key roles in biological systems.
In aqueous solution, Fe3+ forms the hexaaquairon(III) complex [Fe(H2O)6]3+. It is highly prone to hydrolysis, especially
Common ferric salts include ferric chloride FeCl3 and ferric sulfate Fe2(SO4)3, used as coagulants in water
Applications and significance: ferric compounds are used in pigments, pesticides, catalysis, and water treatment; iron(III) is
Safety: ferric salts are corrosive and can irritate skin, eyes, and mucous membranes; ingestion or inhalation
