It depends on the compound. +1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively). In elemental form, its oxidation number is zero.

What is the oxidation number of sulfur in copper sulphate?

In copper sulfate (CuSO4), the oxidation number of sulfur is +6. This is because the oxidation number of copper (Cu) is +2 and oxygen (O) typically has an oxidation number of -2, so the algebraic sum in the compound should be zero.

What is oxidation number of Cu?

If the question is Cu2, then it is equivalent to Cu and the oxidation number for any element is zero. If the question is Cu2+, then the oxidation number is +2.

What is the oxidation number of copper in copper iodide?

Copper iodide has a chemical formula of CuI. In this compound, the oxidation number of copper is +1.

What is the oxidation number for CuCO3?

The oxidation number of copper (Cu) in CuCO3 is +2. Oxygen typically has an oxidation number of -2, and the overall charge of the carbonate ion (CO3) is -2. Therefore, the oxidation number of copper is determined to be +2 in this compound.

What is the oxidation number for copper metal?

The oxidation number for copper metal is 0. This is because copper atoms in their elemental form have a neutral charge, with an equal number of protons and electrons.

What is the oxidation number of copperII?

The oxidation number of copper (II) is +2. This means that copper has lost two electrons in a chemical reaction and has a charge of +2.

What is the oxidation number of copper in CuI?

The oxidation number of copper in CuI is +1. This is because iodine has an oxidation number of -1, and in ionic compounds like CuI, the overall charge must be neutral. Since there is only one iodine atom with a charge of -1, the copper atom must have an oxidation number of +1 to balance the charges.

What is the oxidation number of the copper in CuNH33Cl-NO3?

The oxidation number of copper in CuNH3Cl2NO3 is +1. This is because the overall charge of the complex ion is -1, and the oxidation numbers of N, H, Cl, and O remain the same as their typical values, leaving copper with a +1 oxidation state to balance the charge.

What is the oxidation state of copper in the compound CuCl2?

+2 oxidation state for the Copper. -1 for the Chloride
