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.
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
The oxidation number of oxygen in H2O (water) is -2. Oxygen typically has an oxidation number of -2 in most compounds. In H2O, there are two hydrogen atoms each with an oxidation number of +1, resulting in a total charge of 0 as oxygen contributes -2.
Water, or H2O is a free-standing neutral compound, so it's oxidation number is 0. Its atoms have oxidation number though. Hydrogen's oxidation number in water is +1, and oxygen's is -2.
The oxidation number of oxygen (O) in the compound H2O (water) is -2. Hydrogen typically has an oxidation number of +1 in compounds, so the two hydrogen atoms in water have a combined oxidation number of +2. Since the overall charge of the compound is neutral, the oxidation number of oxygen must be -2 to balance out the charge.
The oxidation number of oxygen in water (H2O) is -2. This is because hydrogen typically has an oxidation number of +1, and the overall charge of water is neutral.

O.S. of H = +1 O.S. of O = -2 O.N. of cpd = 0
The oxidation number of oxygen is -2 in most of its compounds
The oxidation number for oxygen in water (H2O) is -2, since it is more electronegative than hydrogen. The oxidation number for hydrogen in water is +1, since it is less electronegative than oxygen.
The oxidation number of H in H2O is +1, and that of O is -2. Since there are three H2O molecules, the total oxidation number would be 3(+1) + 3(-2) = -3.
Oxygen can have oxidation states of -2, 0, +1/2, or -1. The most common oxidation state of oxygen is -2, such as in water (H2O) and carbon dioxide (CO2).
The oxidation number of an atom in a molecule of water (H2O) is determined based on the electronegativity of the atoms involved. In water, oxygen typically has an oxidation number of -2, while each hydrogen atom has an oxidation number of +1.
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
