The oxidation state is +3.
-1, 0, 1, 2, 3, 4 and 5 oxidation states
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.
Co(NO3)3 is cobalt(III) nitrate, a chemical compound composed of cobalt in a +3 oxidation state and three nitrate ions (NO3−). It typically appears as a bright red or purple crystalline substance and is soluble in water. Cobalt(III) nitrate is used in various applications, including as a catalyst in chemical reactions and in the production of other cobalt compounds. It should be handled with care due to its potential toxicity and environmental impact.
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.
