    Based on the ion shown, which side of water molecules should be touching the ion?
    • A. 

      The partial negative end must be touching the Br^- ion, since like charges between partial negative end (O) in water and the negative ion attract.

    • B. 

      The partial negative end must be touching the Br^- ion, since opposite charges between partial positive end (O) in water and the negative ion attract.

    • C. 

      The partial positive end must be touching the Br^- ion, since opposite charges between partial positive end (H) in water and the negative ion attract.

    • D. 

      None of the above

  • 6.
