Fe^(2+) (aq)+NO_(3)^(-) (aq)+H_(2)SO_(4) (conc.) to Brown ring The brown ring is due to the formation of complex, [Fe(H_(2)O)_(5)NO]SO_(4) . What is the oxidation state of iron in the complex ?

One mole of N_(2)H_(4) loses ten moles of electrons to form a new compound A . Assuming that all the nitrogen appears in the new compound, what is the oxidation state of nitrogen in A ? (There is no change in the oxidation state of hydrogen.)

A 0.1 mole of a metal is burnt in air to form oxide. The same oxide is then reduced by 0.05 M, 4 litres S_(2)O_(3)^(2-) (acidic medium) to +3 oxidation state of metal. What is the oxidation state of metal in oxide ?

H_2 SO_4 is the most important acid used in the chemical industry. Concentrated H_2 SO_4 has quite strong oxidising properties. Oxidation state of S in H_2 SO_4 is

What are the oxidation states of sulfur in the following : SO_(4)^-2

The oxidation state of S in H_(2)S_(2)O_(8) is

What is the average oxidation state of oxygen In S_2O_8^(2-)

STATEMENT-1: The oxidation state of S in H_(2)S_(2)O_(8) is 6. STATEMENT-2: Maximum oxidation state of S is 6 because the maximum oxidation state of an element is equal to number of its valence electrons in it.
