To which part of a water molecule would #Cl^-# be attracted?
To the "positive" end of a water molecule - the hydrogen atoms.
Water has a unique slight "bend" in its bond angles, producing a dipole moment that creates a slightly polar (charged) effect that would not be observed in a linear molecule.
This bend of the hydrogen atoms on each side of the central oxygen atom creates a slight "negative" polarity on the oxygen atom and a slight "positive" one on the hydrogens. In solution, the
