Question
what happens when NaCl(s) is dissolved in water?
(1)Cl-ions are attracted to the oxygen atoms of the water
(2)Cl-ions are attracted to the hydrogen atoms of the water.
(3)Na+ions are attracted to the hydrogen atoms of the water.
(4)no attractions are involved; the crystal just falls apart.
please help & explain the answer !

Crystals dissolve in water because the heat of solution of the ions is enough to overcome the lattice forces holding the crystal together. The water molecules are dipoles with the H end positive and the O end negative. The negative end of water molecules is attracted to the Na^+ and the positive end of the water molecules is attracted to the Cl^- ions. Look in the answers where opposite charges attract (because like charges repel so those won't happen).
