    if you dont want to be specific you can say intermolecular interactions

    These are the answer choices ! he K+ and I– ions. the K+ ion and the negative end of a water molecule. the I– ion and the negative end of a water molecule. the I– ion and the positive end of a water molecule.

    |dw:1355405998873:dw| The oxygen is very electronegative so it will pull electron density away from the hydrogens

    coulomb's law states that opposite charges attract

    Can you make a guess from this information?

    Do you understand that opposite charges attract

    So the answer is A ?

    Well the iodine will pull electrons away the Potassium ion, and it will dissociate away from the K+ because it can form more interactions with the hydrogens than it can with potassium which is a larger element

    Okay so it's not A , so it's D ?

    None of your answers are labeled and it is kind of vague as to which is A and which is B so can you just state the answer you chose and I will confirm it. Source: http://www.chemguide.co.uk/atoms/bonding/hbond.html

    I said this first A. the K+ and I– ions. Then I said D. the I– ion and the positive end of a water molecule.

    The first guess isn't right because K+ and I- will favorably interact, because K+ is missing one electron and thus is rendered with a positive charge and I has an extra electron thus have a negative charge. The reason they can dissociate is because hydrogen bonding can stabilize the negatively charge iodine and thus it can just move away from the positively charged Potassium ion which can be stabilized by the oxygen present in the water molecules
