It separates the different atoms or in the case of salts it separates the ions.
you can visualise by thinking of big Ball surrounded by little balls, in which the big ball is your ion and the little balls are your water molecules.
Water is effective at dissolving salts because of its unique molecular structure that allows it to surround and break apart the ions in the salt, causing them to separate and dissolve in the water. This process is known as hydration and helps salts dissolve in water even though water itself is not a salt substance.
Sodium chloride is dissociated in water: NaCl---------------Na+ + Cl-
The term for this process is "dissociation." In this process, the positive and negative ions of the ionic compound become surrounded by water molecules, allowing them to separate and disperse throughout the solution.
Anhydrous H2CO3 (carbonic acid) is molecular, not ionic. It does not dissociate into ions in the absence of water.
Dissolve them in water. If the solution conducts electricity, then the solute is an ionic compound. If not, then it is a molecular compound.
A molecular compound that ionizes in water to produce protons is a Brønsted-Lowry acid.
Water is a compound consisting of the elements hydrogen and oxygen. The molecular formula for water is H2O.
The process by which some molecular compounds dissolve in water to form ions is called dissolution or ionization. This occurs when the polar water molecules surround and separate the individual ions in the compound, breaking the bonds holding them together. This results in the compound dissociating into its constituent ions.
