Vedclass · Answer

(A) Heavy water $(D_2O)$ is typically obtained by the prolonged electrolysis of ordinary water. However,in the context of laboratory preparation or specific chemical methods,the fractional distillation or exchange reactions are used. Among the given options,none of the chemical additions ($MgCO_3$,$CaSO_4$,$Na_2SO_4$,$CaCO_3$) directly produce heavy water. This question appears to be based on a specific textbook context where the preparation of heavy water is discussed via electrolysis. Given the standard curriculum,if this is a multiple-choice question from a specific source,it is often noted that heavy water is obtained as a byproduct of the electrolysis of water. Since the provided options do not list electrolysis,this question might be flawed or referring to a specific industrial process not listed. However,based on standard chemistry,none of these options are correct. Assuming a correction is needed for a standard exam context,the question is often associated with the electrolysis of water.

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