Vedclass · Answer

(A) Heavy water $(D_2O)$ is obtained by the prolonged electrolysis of water. During electrolysis,the lighter isotope $(H_2O)$ is preferentially decomposed into $H_2$ and $O_2$ gas,leaving behind a residue enriched in $D_2O$. However,in the context of industrial production,the process involves the fractional distillation of water or the exchange reaction between $H_2O$ and $H_2S$. None of the provided options ($MgCO_3$,$CaSO_4$,$Na_2SO_4$,$CaCO_3$) are used to produce heavy water. These salts are typically associated with water hardness. Given the standard curriculum,this question appears to be flawed or based on an incorrect premise regarding chemical saturation.

Which of the following processes can be used to obtain heavy water $(D_2O)$?
