Question

When copper reacts with hot and conc. $H_2SO_4,$ gives

• A. $H_2$
• B. $N_2$
• C. $O_2$
• D. $SO_2$

Answer 1

Answer: (D)

$SO_2$

Answer 2

When copper reacts with hot and conc. $H _{2} SO _{4}$ $SO _{2}$ is produced.
$Cu +2 H _{2} SO _{4} \longrightarrow CuSO _{4}+ SO _{2}+4 H _{2} O$
