Question

When a crystal of sodium chloride is dissolved in water, the oxygen ends of the water molecules are attracted to what part of the sodium chloride

Answer 1

Sodium. Oxygen is electronegative and hece pulls bonding electron towards oxygen atom, creating a partial negative charge on the oxygen atom. As unlike charges attract, it is then attracted to the positively charged sodium ion.

Answer 2

In this situation, the oxygen atoms of the water molecules would be attracted to the sodium atoms from the sodium chloride because oxygen has a charge of -2 and sodium has a charge or +1 (opposite signs attract).

Hope this helps
