[Ni(H2O)3(CO)]SO4Step 1: Identify the complex ion and its counterionCation complex: [Ni(H2O)3(CO)]Counter anion: SO42-Step 2: Identify the charges of the complex ion and its counter ionSO42- is a polyatomic anion with -2 chargeOxidation states: [Ni(H2O)3(CO)]x → X                            SO42- → (-2) x 1 = -2Overall oxidation state: X + (-2) = 0                                      X = 2+Therefore: [Ni(H2O)3(CO)]2+[readmore]Step 3: Name the cation first[Ni(H2O)3(CO)]2+ is a complex cation with an overall charge of +2Step 1: Identify the central metal and the ligandsCentral metal: Ni → NickelLigands:  CO → carbonyl          3 H2O→ aqua         Step 2: Name the ligands in alphabetical order before the metal ion      3 H2O → triaqua      CN → monocarbonylTriaquamonocarbonylStep 3: Determine the oxidation state of the central metal. Name the transition metal and indicate the charge using roman numeralsRecall: For ions, the oxidation number equals the charge[Ni(H2O)3(CO)]2+Oxidation states: Ni → +2 (given)Therefore: Ni2+ → Nickel(II)[Ni(H2O)3(CO)]2+ is triaquamonocarbonylnickel(II)Step 4: Name the anion last with the suffix changed to ‘ate’The anion is SO42- → sulfate[Ni(H2O)3(CO)]SO4 is triaquamonocarbonylnickel(II) sulfate
