Oxidation Number of P in HPO3

21 09 2010Oxidation Number of P in HPO3-2? I keep getting -3 for P but the answer is +5 Someone explain/show how? Update: Yeah I got it before you posted Haha Thanks anyway Answer Save 1 Answer Relevance Anonymous 10 years ago Favorite Answer Because hydrogen is in hydride (H-) form instead of proton (H+) form It's one of those strange quirks of chemistry the electron density in

Chemistry of Aluminum (Z=13)

One +3 oxidation state for Aluminum can be found in the compound aluminum oxide Al 2 O 3 In AlO aluminum monoxide it has a +2 oxidation state and AlH has an oxidation state of +1 Aluminum Compounds Although it does not seem to be particularly reactive aluminum is considered an active metal Its behavior is deceptive because it reacts rapidly with the oxygen in the air to form aluminum

Nitric acid

The molecules of the compounds formed contain nitrogen with an oxidation state of +5 +4 +3 +2 +1 0 +3 respectively For example copper is oxidized with concentrated acid to copper (II) nitrate: Cu + 4HNO3 → 2NO2 + Cu (NO3) 2 + 2H2O and phosphorus to metaphosphoric acid: P + 5HNO3 → 5NO2 + HPO3 + 2H2O Otherwise dilute nitrogenacid with nonmetals Using the example of the reaction

ELEMENTARY CHEMICAL PRINCIPLES

C Oxidation State Oxidation State is characterized by an oxidation number which is the charge one would expect for an atom if it were to dissociate from the surrounding molecule or ion It may be either a positive or negative number usually an integer between -VII and +VII (Roman numerals are generally used to represent oxidation number) This concept is useful in balancing chemical
