Specify the oxidation numbers of the metals in the following coordination entities : [Cr(NH_(3))_(3)Cl_(3)] |
|
Answer» Solution :OXIDATION NUMBERS can be obtained by adding the oxidation numbers of constituents and equating them with the overall charge on the ion, or ZERO, if it is a molecular complex. Assuming x as the oxidation NUMBER of the METAL, we have `x + 0 + 3(-1) = 0` or `x = +3` |
