- A$CO_2$
- ✓$SO_2$
- C$NO_2$
- D$SO_3$
✓
Answer
Correct option: B.
$SO_2$
b
$S \downarrow \,\overset {\operatorname{Re} ducing\,\,\,agent\,} \longleftrightarrow S{O_2} \uparrow \xrightarrow{{Oxidi\sin g\,\,agent\,}}SO_4^{2 - }(aq.)$
$S \downarrow \,\overset {\operatorname{Re} ducing\,\,\,agent\,} \longleftrightarrow S{O_2} \uparrow \xrightarrow{{Oxidi\sin g\,\,agent\,}}SO_4^{2 - }(aq.)$
$SO_2$ is colourless gas.
