The oxidation number of an atom in a compound or in its pure state is its charge when it becomes an ion. This is the value that is the main concern in a redox reaction. It is the one monitored because the corresponding change in this value will mean that the chemical species undergoes...
A convenient preparative route to an Nb(IV) complex, K4[Nb(C2O4)4] · 4H2O · 1/2H2C2O4, is obtained by zinc reduction of concentrated hydrochloric acid-ethanol solutions of niobium pentachloride followed by in situ complexation with oxalate. This direct method of synthesis of an Nb(IV) ...
2. Results and Discussion 2.1. Synthetic Aspects and Characterization The preparation of compound 1 was conducted at 180 ◦C for seven days using a hydrothermal method. When the temperature declined or reaction time was reduced, crystals could not be obtained. The number of amines used in the...

Charge balance requires that the net charge of reactants and products must be equal. We equalize the charges by adding 2 electrons to the products side: C2O4 -2 → 2CO2 + 2e - All elements are identical on both sides, the number of atoms of each element is the same on both sides...
The black micro-arc oxidation (MAO) thermal control coating was prepared in the electrolyte containing Na3PO4, K3[Fe(C2O4)3], C6H11KO7 and NaOH. The complexion mechanism of iron(III) complexes was studied. The effect of adding K3[Fe(C2O4)3] on electrolyte and MAO coating ...
