The oxidation state is +3.
-1, 0, 1, 2, 3, 4 and 5 oxidation states
Cobalt(III) sulfide, represented as Co₂S₃, has a total charge of zero as it is a neutral compound. In this compound, cobalt has a +3 oxidation state, while sulfur has a -2 oxidation state. To balance the charges, two cobalt ions (+6 total) combine with three sulfide ions (-6 total), resulting in a neutral compound. Thus, Co₂S₃ has no overall charge.
The compound formed from cobalt (Co) and bromine (Br) is cobalt(II) bromide, which has the chemical formula CoBr₂. In this compound, cobalt typically exhibits a +2 oxidation state, while bromine is in the -1 oxidation state. Cobalt(II) bromide appears as a reddish-brown solid and is used in various applications, including as a catalyst and in dyes.
The oxidation state of N in NH4+ is -3. Nitrogen typically has an oxidation state of -3 when it is in the ammonium ion (NH4+).
The iconic compound name for Co2(SO4)3 is cobalt(III) sulfate. In this compound, cobalt has a oxidation state of +3, which is indicated by the Roman numeral III in the name. The sulfate ion (SO4) has a charge of -2, and since there are three sulfate ions, the overall charge from cobalt balances to give the formula.
The oxidation state of cobalt(III) is +3. This means that cobalt has lost three electrons.
+3
Cobaltic chloride refers to cobalt(III) chloride, where cobalt has an oxidation state of +3. Cobaltous chloride, on the other hand, refers to cobalt(II) chloride, where cobalt has an oxidation state of +2. The main difference is in the oxidation state of cobalt in the two compounds.
-1, 0, 1, 2, 3, 4 and 5 oxidation states
Cobalt is a transition metal. Its oxidation states are 2 (3).
The cobalt in the formula given has an oxidation number of +3, so that the total charge of the two cobalt ions will balance the total charge of the 3 oxide ions, which have an oxidation number of -2 each.
Co = +2 oxidation C = +4 oxidation O = -2 oxidation
0 in elemental form, +2 and +3 in its compounds
-1, 0, 1, 2, 3, 4 and 5 oxidation states
Variable oxidation state refers to (an element) having more than 1 oxidation states. e.g. Cobalt having oxidation states +2 & +3, similarly Fe having +2 & +3, Cr +2, +3 & +6
+3
The formula for cobalt(II) fluoride is CoF2, where cobalt has a +2 oxidation state and fluorine has a -1 oxidation state.
