Vedclass · Answer

(D) Artificial smoke screens are produced using $TiCl_4$ (Titanium tetrachloride). When $TiCl_4$ is released into the atmosphere,it reacts with moisture in the air to form $TiO_2$ (Titanium oxide) and $HCl$ (Hydrogen chloride) gas. The reaction is: $TiCl_4 + 2H_2O \rightarrow TiO_2 + 4HCl$. The resulting $TiO_2$ particles form a dense white smoke that acts as a screen.
