Question

Why are ionic crystals soluble in water?

A. The covalent bonds in the ionic crystal can easily reshape to bond with the water molecules, allowing it to dissolve.

B. The water slides the layers of the ionic crystal lattice so that positive charges line up with positive charges. They repel

each other and break the crystal apart.

C. Partial charges in water molecules attract the charges in the atoms of the ionic crystal, pulling the atoms off the crystal.

D. They are not. The positive and negative charges in the ionic lattice are stronger than the partial charges in the water.

Answer 1

Answer:

C. Partial charges in water molecules attract the charges in the atoms of the ionic crystal, pulling the atoms off the crystal.

Explanation:

Water consists of partial positive and hydrogen ions and partial negative oxygen ions. The ionic crystals also dissociate into ions when in water.These partial charges and ability of ionic compounds to dissociate in water are the main reason why ionic crystals dissolve in water.

The partial charges in the water molecules form a strong attraction towards the charges in the atoms of ionic crystals. This then pulls the atoms from the crystals and ends up in the dissolution of the ionic crystals.
