Homework Help: Dipole moment of water

  1. Nov 11, 2005 #1
    Certain molecules have built-in dipole moments. The dipole moment of water is unusually large: 6.1 x 10-30C.m. How does this account for the effectiveness of water as a solvent?

    Looks like a standard textbook question.

    This thread shoud go into the Coursework section where it will be subject to the requirement that you first tell us what you think.

    OK, I did not realise this is a HW-type question :blushing:.

    So, in a water molecule, electrons cluster around the oxygen atom and the molecule is bent at an angle of 105 degrees. How does this make water an excellent solvent?

    The molecule is polar, that should be the "bridge" between clustered electrons and excelent solvents.

    I can't blame you though. The question is worded all wierd but the concept is nevertheless the same, so you are better off researching about this.
