Answer:

The products formed when phosphorus reacts with concentrated nitric acid are phosphoric acid (H_{3} PO_{4}), nitrogen dioxide (NO_{2}) and water (H_{2} O).

Explanation:

Phosphorus is a strong reducing agent and has a very strong affinity towards oxygen.

Since phosphorus is a strong reducing agent, it reduces nitric acid to nitrogen dioxide and itself gets oxidized to phosphoric acid.

The oxidation state of phosphorus changes from 0 to +5, that is phosphorus gets oxidized. The oxidation state of nitrogen changes from +5 to +4, that is nitrogen gets reduced.

Thus the balanced chemical reaction can be written as:

P_{4} +20HNO_{3}20NO_{2} +4H_{3}PO_{4} +4H_{2} O
