What is the oxidation number of HSO4?

Number for hydrogen is +1.Number for sulphur is +6.Number for oxygen is -2.The oxidation number for the overall ion is -1. Oxidation numbers for hydrogen and oxygen are +1 and -2 respectively. By balancing the charges, the sulfur atom is in +6 state.


Most common oxidation number of combined oxygen?

the most common oxidation number for oxygen is -2.


Why oxidation number for oxygen in H2O is -2?

In H2O, each hydrogen atom has an oxidation state of +1. Since the overall charge of the molecule is zero, the oxygen atom must have an oxidation state of -2 to balance out the charges and make the molecule neutral. This is a common rule based on the electronegativity of oxygen.


What is the oxidation numbers of bromine?

Bromine has an oxidation number of negative one, except when with oxygen or flourine.


What is the Oxidation numbers for element PbO2?

The oxidation number for Pb in PbO2 is +4. Oxygen in compounds is typically -2, so with two oxygens, the total oxidation number contributed by oxygen is -4. This means that the oxidation number of Pb must be +4 to balance the charges.


What is the oxidation number of HClO2?

In HClO2, the oxidation number of hydrogen (H) is +1 since it is typically +1 in compounds, the oxidation number of chlorine (Cl) is +3, and the oxidation number of oxygen (O) is -2. The sum of the oxidation numbers in a compound must equal zero, so in HClO2, the oxidation number of chlorine (+3) is balanced by the oxidation numbers of hydrogen (+1) and oxygen (-2).


What are the oxidation numbers of Lead?

It depends on the compound. Lead can have an oxidation state of either 2+ or 4+


What is the sum of the oxidation numbers for P2O5?

The sum of the oxidation numbers for P2O5 is zero. In P2O5, the oxidation number for phosphorus is +5, and each oxygen atom has an oxidation number of -2. Since there are five oxygen atoms, the total sum of the oxidation numbers is 2(+5) + 5(-2) = 0.


What are the oxidation numbers of the elements in the following compound of Fe2O3?

The oxidation number of Fe in Fe2O3 is +3 because oxygen typically has an oxidation number of -2 and there are 3 oxygen atoms for every 2 iron atoms in the compound, making the overall charge -6 for oxygen. To balance the charges, each iron atom must have a charge of +3.


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 carbon in carbonate?

The oxidation number of carbon in carbonate (CO3^2-) is +4. In the carbonate ion, each oxygen atom has an oxidation number of -2, so the overall charge of the ion is -2. This means the oxidation number of carbon must be +4 to balance the charges in the compound.
