(D) The reaction between dilute $HCl$ and $CaCO_3$ is: $CaCO_3(s) + 2HCl(aq) \rightarrow CaCl_2(aq) + H_2O(l) + CO_2(g)$.The gas evolved is carbon dioxide $(CO_2)$.$CO_2$ is a colourless and odourless gas.$CO_2$ is acidic in nature because it forms carbonic acid $(H_2CO_3)$ when dissolved in water.$CO_2$ is not considered a poisonous gas (it is a natural component of the atmosphere).$CO_2$ is moderately soluble in water,not the least soluble gas compared to others like $H_2$ or $N_2$.Therefore,the statements that it has the least solubility and that it is poisonous are both technically incorrect,but in the context of standard chemistry questions,$CO_2$ is not poisonous.

Which of the following statements is not correct regarding the gas evolved by the reaction of dilute $HCl$ on $CaCO_3$?
