Question

question 36(multiple choice worth 2 points) (02.01 mc) which of the following best explains how water is able to dissolve ionic substances? the positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart. the strong hydrogen bond on water attracts the positive end of the ionic molecule and breaks the ionic bond. water acts as a proton donor for the negative end of the ionic molecule to attract the anion and form a new ionic molecule. the water molecule shares its electrons in a covalent bond with the positive end of the ionic molecule to break the ionic bond.

Explanation:

Water is a polar molecule with positive and negative ends. When dissolving ionic substances, the positive end of the water molecule is attracted to the negative ion (anion) of the ionic compound, and the negative end of the water molecule is attracted to the positive ion (cation) of the ionic compound. This attraction pulls the ions in the ionic compound apart, breaking the ionic bonds and dissolving the substance.

Answer:

The positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart.
