Q. In one of the following reactions HNO_{3} does not behave as an oxidizing agent Identify it
A) I_{2} + 10HNO_{3} ⟶ 2HIO_{3} + 10NO_{2} + 4H_{2}O
B) 3Cu + 8HNO_{3} ⟶ 3Cu(NO_{3})_{2} + 2NO + 4H_{2}O
C) 4Zn + 10HNO_{3} ⟶ 4Zn(NO_{3})_{2} + NH_{4}NO_{3} + 3H_{2}O
D) 2HNO_{3} + P_{2}O_{5} ⟶ 2HPO_{3} + N_{2}O_{5}
Explanation
(d)
In the reaction,
2HNO_{3}+P_{2}O_{5}⟶2HPO_{3}+N_{2}O_{5}
HNO_{3} does not behave as an oxidising agent because in this reaction P_{2}O_{5} shows dehydrating property . It removes water molecule from HNO_{3}
