Question

can someone help me please?
Study the Figure. When the ionic compound KI is dissolved in water, the I– ions are pulled into solution by the attraction between
the 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.

Answer 1

Can't see the figure because I need a login. But I can explain the principle behind dissolution. Generally speaking, the reason why one compound (the solute) dissolves in another (the solvent) is that the solvent is able to interfere with the bonds that hold the solute together and substitute itself in, separating one solute molecule from others in the sample (for nonpolar solutes and solvents) or even elements of the solute itself (for ionic solutes/polar solvents).

In your example, you have an ionic solute, KI, dissolving in a highly polar solvent, water. Water has a permanent dipole that is able to effectively compete with the ionic bond of KI and so can create a new bond with it. In this case, K+ would interact with the negative end of the water molecule while I- would interact with the positive end.

Answer 3

Yup I thought it was something like that. My answer doesn't change.
