This change is called oxidation (increase of ox. state) or reduction (decrease)
Lithium atom become the cation Li+.
Use for decolourizing of Ferric and Ferrus oxide , green colour to colourless. But Selenium have many oxidation state and can change oxidation state when furnace condition change Reduction to Oxidation.
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
It goes from +1 to 0.
It goes from +1 to 0
The principal oxidation state of NA in NA2O2 and K in KO2 is +1
In NaBrO3 the oxidation state of sodium (Na) is 1+, the oxidation state of bromine is 5+ and the oxidation state of each oxygen atom is 2-
Not sure what L(s) is supposed to be, but regardless, the oxidation state of Na changes from 1+ in NaOH to zero in Na(s).
This is a neutral compound. Na shows the +1 OXIDATION NUMBER.
This change is called oxidation (increase of ox. state) or reduction (decrease)
Sodium Oxide, or NaOH, has no oxidation state. It has a charge, which is zero. The elements that make up NaOH, however, do have oxidation states. The oxidation state of sodium (Na) is +1, and it will forever be +1 because it is impossible for it to be anything else, no matter what situation. The same applies for Hydrogen. Oxygen has an oxidation state of -2, and almost always will have an oxidation state of -2. There is one notable exception: H2O2. In this case, since the total charge of the compound is neutral and the oxidation state of Hydrogen must be +1 and, seeing as there are two hydrogens, bringing the overall charge up to 2, the oxidation state of oxygen must be -1. If it was -2, then the molecule would have an overall charge of -2.
It goes from 0 to +1
it goes from +1 to 0
Lithium atom become the cation Li+.
zero bcoz the oxidation no of element in free state is zero
