In H3PO3 each H is 1+ for a total of 3+. Each O is 2- for a total of 6-. So, there is 3+ and 6- giving a net of 3-. In order to make the molecule neutral, P must have an oxidation state of 3+.
-3, -2, -1, 0, 1, 2, 3, 4 and 5 oxidation states
The oxidation state of PPh3 is zero !
The oxidation state of P in PO4(3-) is 5.
9
Fe = +3 oxidation state Cl = -1 oxidation state
It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
0, 1 and 2 oxidation states
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-
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
-2 oxidation state
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
Fe = +3 oxidation state Cl = -1 oxidation state
O = -2 oxidation state H = +1 oxidation state
Mg = +2 oxidation state P = +5 oxidation state O = -2 oxidation state
It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
0, 1 and 2 oxidation states
The oxidation state of calcium is +2.
