The poles of water molecules share electrons with the ions in ionic compounds.
The poles of water molecules share electrons with the ions in ionic compounds.

The opposite charges of ionic compounds repel each other, so water molecules can separate the ions.

The electron transfer in ionic compounds results in ions that are attracted to water’s poles.

Answer 1

The correct response is:

The electron transfer in ionic compounds results in ions that are attracted to water’s poles.

This is because water is a polar molecule, meaning it has a partial positive charge on one end (the hydrogen atoms) and a partial negative charge on the other end (the oxygen atom). When ionic compounds dissolve in water, the positively charged ions are attracted to the partial negative charge of the oxygen, and the negatively charged ions are attracted to the partial positive charge of the hydrogens, allowing the ionic compound to dissolve.
