MCQ
Heavy water is :
- AWater with mercury compounds
- BWater with chlorides and sulphates of $Ca$ and $Mg$
- CWater with bicarbonates of $Ca$ and $Mg$
- ✓Deuterium oxide
✓
Answer
Correct option: D.
Deuterium oxide
Heavy water is deuterium oxide $\ce{(D_2O)}$. Ordinary water contains a fraction $(1$ in $6000$ parts$)$ of heavy water. On large scale, it is produced by repeated electrolysis of ordinary water containing alkali. It is also produced by repeated distillation and condensation.
