Which one of the following statements about water is FALSE?

AWater can act both as an acid and as a base.
BThere is extensive intramolecular hydrogen bonding in the condensed phase.
Correct Answer
CIce formed by heavy water sinks in normal water.
DWater is oxidized to oxygen during photosynthesis.

Solution

Water is neutral. It acts both as a base and as an acid.

There is extensive intermolecular hydrogen bonding in the condensed phase.

The density of heavy water is more than the density of water, therefore, $$D_2O$$ sinks in normal water.

Reaction of photosynthesis:
$$6CO_2+6H_2O\longrightarrow C_6H_{12}O_6+6O_2$$
