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.
When ice changes to water, the arrangement of atoms does not change. The individual water molecules retain the same structure and bonding configuration, but the intermolecular forces holding the molecules together weaken, allowing them to move more freely, resulting in the transition from a solid to a liquid state.

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.
The concentration of the salt solution, or salinity. It changes as shown in the related link below.
Carbon atoms readily link to one another to form a chain
When water changes to ice, the arrangement of water molecules changes from a more randomly structured liquid form to a more orderly crystalline form. The atoms themselves do not change in terms of their chemical composition, but their arrangement and movement are altered to form the solid structure of ice.

The link up of atoms in ice remains the same when it turns to water. However, the arrangement of the atoms changes from a rigid, crystalline structure to a more fluid and less ordered arrangement.

It is a physical change because only the phase of the salt actually changes - the two compounds do not react. The salt dissolves in the water, but if the water evaporates, the salt is left behind in its solid state.
