Question:
Knowing the properties of H2O and D2O, do you think that D2O can be used for drinking purposes?
Solution:
Heavy water (D2O) acts as a moderator, i.e., it slows the rate of a reaction. Due to this property of D2O, it cannot be used for drinking purposes because it will slow down anabolic and catabolic reactions taking place in the body and lead to a casualty.
