The molecule with the formula Pb(C2O4)2 is known as Lead(II) Oxalate. It is composed of lead ions (Pb²⁺) and oxalate ions (C2O4²⁻).
Oxalic acid, which is the source of the oxalate ions, has two carboxyl (-COOH) groups. When the oxalic acid loses protons, it forms the oxalate ion. In the case of Lead(II) Oxalate, each lead ion is complexed with two oxalate ions.
Lead(II) Oxalate is used in various applications, including in ceramics and as a pigment. It’s important to note that while lead compounds can be useful, they can also be toxic, so proper handling is essential.
