The nitrate anion is select one: a. a strong acid. b. a strong base. c. amphoteric. d. a strong reducing agent. e. a strong oxidizing agent.

Option (e) is the correct answer.

Explanation:

Chemical formula of a nitrate ion is and it acts as a strong oxidizing agent because it itself gets reduced easily.

As we know that an oxidizing agent tends to oxidize other substances by itself gaining electrons. As a result, there will occur a decrease in its oxidation state.

The oxidation number of nitrogen in is +5. So, it gains electrons and helps in oxidizing other substances.

Thus, we can conclude that the nitrate anion is a strong oxidizing agent.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
