Question

question 8 of 15
which of the following properties of water molecules increases the ability of water to be a good solvent?
a. water molecules contain polar covalent bonds, which affect the polarity of the molecules and increase their ability to dissolve other molecules.
b. water is a very small molecule and therefore can fit in the space between solute molecules.
c. the bonds between the hydrogen and oxygen atoms are very small, allowing many water molecules in a small space.
d. the mass of water is very low, and therefore it can bond with many other molecules.

Explanation:

Polar - covalent bonds in water make it polar. Polar solvents dissolve polar solutes well due to electrostatic interactions. Other options do not correctly explain water's solvent ability.

Answer:

A. Water molecules contain polar covalent bonds, which affect the polarity of the molecules and increase their ability to dissolve other molecules.
