When copper is heated with conc. $HNO_3$ it produces :
Updated On: Apr 17, 2024
- $Cu(NO_3)_2$ and $NO$
- $Cu(NO_3)_2,NO$ and $NO_2 $
- $Cu(NO_3)_2$ and $N_2O$
- $Cu(NO_3)_2$ and $NO_2$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
When copper react with conc. ${HNO_3}$ reddish brown gas ${NO_2}$ evolved
${Cu + 4HNO_3 -> Cu(NO_3)_2 + 2H_2O + 2NO_2}$
${Cu + 4HNO_3 -> Cu(NO_3)_2 + 2H_2O + 2NO_2}$

Concepts Used:
P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
