Problem: Name the salt [Ni(H2O)3(CO)]SO4. The oxidation number of nickel is +2.
FREE Expert Solution
[Ni(H2O)3(CO)]SO4
Step 1: Identify the complex ion and its counterion
Cation complex: [Ni(H2O)3(CO)]
Counter anion: SO42-
Step 2: Identify the charges of the complex ion and its counter ion
SO42- is a polyatomic anion with -2 charge
Oxidation states: [Ni(H2O)3(CO)]x → X
SO42- → (-2) x 1 = -2
Overall oxidation state: X + (-2) = 0
X = 2+
Therefore: [Ni(H2O)3(CO)]2+
