Question
Knowing the properties of $\mathrm{H}_2 \mathrm{O}$ and $\mathrm{D}_2 \mathrm{O}$, do you think that $\mathrm{D}_2 \mathrm{O}$ can be used for drinking purposes?
✓

Answer

No, heavy water $\left(\mathrm{D}_2 \mathrm{O}\right)$ cannot be used for drinking purposes because it is injurious to health due to presence of $\mathrm{D}^{+}$ ions. Heavy water of high concentration retards the growth of plants and animals. Heavy water has germicide and bactericide properties.
