Question

- How does dissolving a salt molecule in water make its atoms ionize?​

Answer 1

Answer:

Dissolving a salt molecule in water does not make its atoms ionize.

Explanation:

• Salt is not a molecular substance. It is an ion collection with both positive and negative charges.
• When these salts are added to water, the ions separate and are surrounded by polar water molecules, preventing them from adhering to one another. This is the dissolving process.

• The atoms in salt are already ionized, therefore adding water has no effect on their ionization. Instead, the water molecules adhere to the salt's already-formed ions.

Answer 2

Answer:

The dissociation of a salt molecule in water occurs due to the polar nature of water and the electrostatic attractions between the water molecules and the ions in the salt molecule.

Explanation:

When a salt molecule dissolves in water, the polar water molecules interact with the ions in the salt molecule, cau sing it to break apart or dissociate into its constituent ions. For example, when table salt (NaCl) dissolves in water, the water molecules surround and sepa rate the Na+ and Cl- ions, causing them to become hyd rated and separated from one another.

The dissociation of the salt molecule is due to the fact that water molecules have a polar nature. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom has a partial negative charge, while the hydrogen atoms have a partial positive charge. This creates an electro static attraction between the water molecule and the ions in the salt molecule.

The positive end of the water molecule (the hydrogen atoms) is attra cted to the negative ion in the salt molecule (the chloride ion, Cl-), while the negative end of the water molecule (the oxygen atom) is attracted to the positive ion in the salt molecule (the sodium ion, Na+).

As a result of these attractions, the ions become separated from one another and are surrounded by water molecules. This process is called hydration, and it helps stabilize the ions in solution by reducing their interactions with one another.
