The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
Neutral atoms are not identical to ions.
A chemical change.
The polarity of the water molecule causes an ionic compound to dissolve in water. The slightly negative oxygen atoms of the water molecules attract the positive ions, and the slightly positive hydrogen atoms of the water molecules attract the negative ions. This breaks the ionic bonds and the ions are surrounded by water molecules, preventing them from reforming ionic bonds. Refer to the related link for an illustration and more information.

The process of removing salt from saltwater is known as desalination. In this process, the salt water is heated until the water turns to steam. The steam is then funnelled of and cooled so that it turns back to water. See the link below for more information

Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.
