Solution
Water dissolves salts through a process called solvation. Here's a step-by-step explanation:
-
Water molecules are polar, meaning they have a positive end and a negative end. This is due to the difference in electronegativity between the hydrogen and oxygen atoms in a water molecule.
-
Salt, such as sodium chloride (NaCl), is an ionic compound, meaning it's made up of positively charged ions (sodium, Na+) and negatively charged ions (chloride, Cl-).
-
When salt is added to water, the positive end of the water molecules are attracted to the chloride ions, and the negative end of the water molecules are attracted to the sodium ions.
-
The attraction between the water molecules and the ions in the salt is strong enough to break the ionic bonds in the salt, causing the salt to dissolve.
-
The water molecules surround the individual ions, keeping them separated and preventing them from re-forming into a solid. This is known as hydration.
-
The salt appears to disappear in the water because the ions are dispersed throughout the solution, but the salt is still present in the water.
So, the correct answer is "by water molecules breaking the bonds in salt" and "by salt molecules surrounding the water molecules".
