What is the oxidation number for chromium?
The oxidation number for chromium can vary depending on the compound it is part of. In general, chromium can have oxidation states ranging from -2 to +6.
What is the oxidation number for k2cro4?
In K₂CrO₄, the oxidation number of potassium (K) is +1, and the oxidation number of oxygen (O) is -2. Since the compound is neutral, the oxidation number of chromium (Cr) can be calculated as follows: 2(+1) + Cr + 4(-2) = 0. Solving for chromium, the oxidation number of chromium in K₂CrO₄ is +6.
What is the change in oxidation number of chromium when Na2Cr2O7 becomes Crl3?
The oxidation number of chromium changes from +6 in Na2Cr2O7 to +3 in CrCl3. This represents a reduction in oxidation number by three units.
What is the oxidation number of the phosphorus in chromium III phosphate?
The oxidation number of phosphorus in chromium(III) phosphate is +5. In chromium(III) phosphate, each chromium ion has a +3 oxidation state, and the overall compound is electrically neutral, so the oxidation number of phosphorus must be +5 to balance the charges.
What is the oxidation number of chromium for CrBr2?
The oxidation number of chromium in CrBr2 is +2. This is because bromine typically has an oxidation number of -1 and there are two bromine atoms in CrBr2, leading to a total oxidation number of -2. The oxidation number of chromium must therefore be +2 to balance the charges.

Why the oxidation number of Cr2O72- is 6?
It is true for chromium. But O shows 2asthe oxidation number.
What is the oxidation number of chromium in K2Cr2O7?
The oxidation number of chromium in K2Cr2O7 is +6. Each potassium ion has an oxidation state of +1, and each oxygen atom has an oxidation state of -2. By setting up an equation based on the overall charge of the compound, it can be determined that chromium has an oxidation state of +6.
What is the oxidation number of each atom individually of CrO3?
In CrO3, the oxidation number of chromium (Cr) is +6 and the oxidation number of oxygen (O) is -2. This is because oxygen typically has an oxidation number of -2, and there are three oxygen atoms in CrO3 to give a total charge of -6. To balance the charge, the chromium atom must have an oxidation number of +6.
What are the oxidation numbers in chromiumIII oxide?
In chromium(III) oxide, the oxidation number of chromium is +3 and the oxidation number of oxygen is -2. This compound has the chemical formula Cr2O3.
What is the oxidation number of chromium in potassium dichromate?
The oxidation number of chromium in potassium dichromate is +6. Each oxygen has an oxidation number of -2, and since the compound is neutral, the oxidation number of potassium is +1. This means the two chromium atoms in potassium dichromate each have an oxidation number of +6 to balance the charges.
What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
What is the oxidation number of CrO42?
The oxidation number of chromium (Cr) in CrO4^2- is +6. Since each oxygen atom has an oxidation number of -2, and the overall charge of the polyatomic ion is -2, the oxidation number of chromium can be determined by solving the equation: (oxidation number of Cr) + 4(-2) = -2.
