Vedclass · Answer

(B) $1$. Both $CO_2$ and $SO_2$ react with lime water $(Ca(OH)_2)$ to form calcium carbonate $(CaCO_3)$ or calcium sulfite $(CaSO_3)$,which are white precipitates,thus turning lime water milky.$2$. $SO_2$ acts as a reducing agent and turns acidified $K_2Cr_2O_7$ solution green due to the formation of $Cr_2(SO_4)_3$,but $CO_2$ does not.$3$. $SO_2$ can act as both an oxidising and a reducing agent,while $CO_2$ is generally inert in redox reactions under standard conditions.$4$. Since only statement $B$ is correct,the options provided are technically flawed. However,in many contexts,the question aims to highlight the common property of turning lime water milky.
