How can $D_2O$ be prepared from water? Mention the physical properties in which $D_2O$ differs from $H_2O$ . Give at least three reactions of $D_2O$ showing the exchange of Hydrogen with deuterium.

Answers (1)

Extended electrolysis of water can produce D2O; it differs from water as it has a high molecular mass.

		$H_2O$	$D_2O$
1.	Boiling Point	373K	373.4K
2.	Melting Point	273K	276.8K
3.	Molecular Mass	18.016	20.3

Reactions showing the exchange of Hydrogen with deuterium

$NaOH + D_{2}O \rightarrow NaOD + HOD$
$HCl + D_{2}O \rightarrow DCl + HOD$
$NH_{4}Cl + D_{2}O \rightarrow NH_{3}DCl + HOD$
