When KCl dissolves in water:
the Cl- ions are attracted to the partially negative oxygen atoms of the water molecule.
the K+ ions are attracted to Cl- ions on the KCl crystal.
the K+ ions are attracted to the partially positive hydrogen atoms of the water molecule.
the K+ ions are attracted to the partially negative oxygen atoms of the water molecule.
the Cl- ions are attracted to dissolved K+ ions.
Please explain!
