Question

The polarity of the water molecule aids in dissolving compounds. This is demonstrated by all but which statement?A)The water molecules group together in clumps.B)The partial negative oxygen atom end of the water molecule surround cations.C)The partial positive hydrogen atom end of the water molecule surround anions.D)The water molecules also dissolve nonelectrolytes by creating a hydration sphere around the molecule.

Answer 1

Answer:

A

Explanation: this statement does not demonstrate how water molecules help dissolve compounds.

Answer 2

Answer:

The correct option is;

A) The water molecules group together in clumps.

Explanation:

To answer the question, we look at each option as follows

A)  The water molecules group together in clumps

This does not aid dissolution of compounds as clumping excludes non polar molecules, making them less soluble.

B) The partial negative oxygen atom end of the water molecule surround cations.

When an ionic compound such as NaCl is dissolved in water, the oxygen atoms surround the positive Na⁺ cations in the solution.

C) The partial positive hydrogen atom end of the water molecule surround anions

When the ionic NaCl compound  is dissolved in water, the hydrogen atoms surround the negative Cl⁻ anions  in the solution.

D) The water molecules also dissolve nonelectrolytes by creating a hydration sphere around the molecule.

Water is able to dissolve nonelectrolytes  by creating an hydration sphere or hydration shell around the molecule.
