Question

List the reason for the oxidizing properties of Nitric Acid.

Answer 1

Hint: Nitric acid (\[HN{O_3}\]) is a colourless, fuming, and extremely corrosive liquid with a freezing point of - 42 degrees Celsius (- 44 degrees Fahrenheit) and a boiling point of 83 degrees Celsius (180 degrees Fahrenheit). This is a popular laboratory reagent as well as an effective industrial chemical used in fertiliser and explosive production. It's poisonous and can cause serious burns.

Complete answer: Nitric acid ($HNO_3$) is a colourless, fuming, and extremely corrosive liquid with a freezing point of - 42 degrees Celsius (- 44 degrees Fahrenheit) and a boiling point of 83 degrees Celsius (180 degrees Fahrenheit). This is a popular laboratory reagent as well as an effective industrial chemical used in fertiliser and explosive production. It's poisonous and can cause serious burns.
Nitric acid decomposes into a brownish yellow solution of water, nitrogen dioxide, and oxygen. It is a potent oxidising agent and a strong acid that is fully ionised into hydronium (\[{H_3}{O^ + }\]) and nitrate (\[N{O_3}^ - \])ions in aqueous solution (one that acts as electron acceptor in oxidation-reduction reactions).
Properties:
\[HN{O_3}\] is a strong oxidizer.
N's oxidation state shifts from \[{N^{ + 5}}to{N^{ + 3}}\]. The degree of oxidation is determined by:
 Acid concentration
The greater the oxidation, the lower the acid concentration.
 Nature of element
The more reactive an element is, the more oxidation it undergoes.
