What is the oxidation no of calcium in compound caocl2?

The oxidation number of calcium in the compound CaOCl2 is +2. In compounds, the sum of the oxidation numbers must equal zero, and since oxygen has an oxidation number of -2 and chlorine has an oxidation number of -1, the calcium ion must have an oxidation number of +2 to balance the charges.


What is the Oxidation number of calcium carbonate?

The oxidation number of calcium in calcium carbonate (CaCO3) is +2. The oxidation number of oxygen is -2. By comparing the charges in the compound, you can deduce that the oxidation number of carbon in calcium carbonate is +4.


Oxidation number of calcium in bleaching powder?

The oxidation number of calcium in bleaching powder (calcium hypochlorite) is +1. In the compound Ca(ClO)2, the total oxidation numbers of chlorine (-1) and oxygen (-2) balance out to zero, so calcium must have an oxidation number of +1 to maintain overall charge neutrality.


What is the oxidation number of Ca(NO3)2?

The sum of the oxidation numbers is zero for the compound.


What is the oxidation number for calcium and nitrate?

Calcium is a element. Nitrate is a ion. Calcium shows +2.


What is the oxidation number in CaF2?

Fluorine's oxidation number is -1. Since there are four fluorine atoms, the total oxidation number for the fluorine portion of the molecule is -4. The carbon atomwould have to have an oxidation number of +4 so that the compound would have an overall oxidation number of 0.


What is the oxidation number of Ca?

The oxidation number of Calcium (Ca) is +2


What is the oxidation number of calcium in Ca3 PO4 2?

The oxidation number of calcium in Ca3(PO4)2 is +2. This is because each phosphate ion (PO4)^3- has a charge of -3, and there are two phosphate ions in Ca3(PO4)2. Calcium has a +2 oxidation state to balance the -6 charge from the two phosphate ions.


What is the oxidation number O in cao2?

-1. In simple inorganic compounds other than peroxides and superoxides, oxygen almost always has an oxidation number of -2, but since calcium cations always have an oxidation number of +2, in this compound, the two oxygen atoms must have only -1 charge each. This compound is calcium peroxide, one of the exceptions noted above.


What is the oxidation number of BH4 in the compound?

The oxidation number of BH4 in the compound is -1.


What is the oxidation number of Cr in CaCrO4?

+2 for Ca, +6 for Cr, -2 for each O


Is the oxidation number in CaCl2 is 3?

No, the oxidation number of CaCl2 is not 3. In CaCl2, calcium (Ca) has an oxidation state of +2, and each chlorine atom (Cl) has an oxidation state of -1. This combination allows for the compound to have a neutral charge.
