Solubility Studies of Iron(III) Oxides and Hydroxides

Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. Sometimes this addition causes both the substance and water molecule to split into two parts. In such reactions, one fragment of the target molecule (or parent molecule) gains a hydrogen ion. It breaks a chemical bond in the compound. WebReaction of iron with acids. Iron metal dissolves readily in dilute sulphuric acid in the absence of oxygen forming Fe (II) ions and H 2. In aqueous solution Fe (II) is present as the complex [Fe (H 2 O) 6] 2+.
