Why does copper have two oxidation states?
It’s an energy balance. Donating additional valence electrons to make higher oxidation states costs energy. In the case of copper it usually works for donating one 3d electrons plus the 4s electron for +2 , but getting to +3 is too much.
What is the charge of Cu in cuso4?
2+
What is the oxidation number of feso4?
+2
What is the oxidation number of pb3o4?
83
What is the oxidation number for N in NO2?
+4
What is the oxidation number of N in No 21?
Since the entire polyatomic nitrite ion has an overall ionic charge of -1 the nitrogen ion in the molecule must have a charge of +3. Combining the -4 of the oxygen and the +3 of the nitrogen we achieve the -1 charge of the nitrite ion. Therefore the oxidation state of nitrogen in a nitrite polyatomic molecule is −3 .
What is water’s oxidation number?
The formula for water is . The oxidation number of hydrogen is +1. Since there are two of them, the hydrogen atoms contribute to a charge of +2. The water molecule is neutral; therefore, the oxygen must have an oxidation number of to balance the charge.
What is the oxidation number of PbO?
What is the oxidation number of Na3PO4?
In Na3PO4 Na oxidation state is +1 and O oxidation state is -2. So in Na3PO4 3-Na got +3, and 4-O got -8 charge which gives coverall -5 charge.
What is red lead powder?
A bright orange powder with strong Preservative properties. When mixed with linseed oil putty, it makes ‘red lead putty’ for use as stopping in seams below the waterline on wooden craft.
