Question:medium
Which of the following statements is not correct regarding the gas evolved by the reaction of dilute $\text{HCl}$ on $\text{CaCO}_3$?
Which of the following statements is not correct regarding the gas evolved by the reaction of dilute $\text{HCl}$ on $\text{CaCO}_3$?
Show Hint
Carbon dioxide is an acidic oxide, slightly soluble in water, and non-toxic (but can cause asphyxiation). Carbon monoxide ($\text{CO}$), on the other hand, is a highly poisonous gas that binds irreversibly to hemoglobin.
