Verified step by step guidance1
Understand the naming conventions for coordination compounds. The name 'dibromotetracarbonylstannate(IV) sulfate' suggests a complex ion with tin (Sn) as the central metal, surrounded by ligands and counter ions.
Identify the ligands and their quantities from the name. 'Tetracarbonyl' indicates four carbonyl (CO) groups, and 'dibromo' indicates two bromine (Br) atoms attached to the tin center.
Recognize the oxidation state of the central metal. 'Stannate(IV)' indicates that tin is in the +4 oxidation state.
Determine the counter ion from the name. 'Sulfate' suggests the presence of sulfate ions (SO₄²⁻) as the counter ion.
Construct the chemical formula based on the identified components: [Sn(CO)₄(Br)₂]SO₄. This formula represents the complex ion with tin surrounded by four carbonyl groups and two bromine atoms, balanced by a sulfate ion.
