The Molecules
On the molecular level, water molecules move more or less randomly, driven mostly by entropy. On the cellular level, water follows solute concentration. This is the basis of osmosis and diffusion.
The first step in the dissolving process is "The solvent molecules surround the solute particles".
The process if solute disappearing into solvent is called dissolving. This means that the solute and solvent are of like polarity or the solute was broken up into ions.
Depending on the molecular mass of the solute.
The Molecules
When a solute dissolves it breaks apart into its individual particles. The solute and solvent particles mix together and become totally mixed up. That's why a solution is a mixture! As the solute and solvent particles become mixed up, no matter is lost. The overall mass stays the same.
Dissolving is a familiar process. Salt, for example, dissolves readily in water, as does sugar in coffee. On a molecular level, dissolving consists of the molecules of a solute -- salt or sugar -- encountering and pairing up with the molecules of a solvent -- water or coffee. Only when a successful pairing is made can the solute dissolve into the solvent. To increase the rate at which a solute dissolves, you must increase the rate at which molecules within the solute can encounter and subsequently pair with molecules within the solvent.

A solute will dissolve in a solvent when the attractive intermolecular forces between the molecules of the solvent and the molecules of the solute are greater than the attractive forces between one solute molecule and another. Thus the solute is effectively 'pulled apart' (on a molecular level at least) by the solvent and it's molecules become 'suspended' between the molecules of the solvent at which point the solute is said to be in solution or dissolved.
The first step in the dissolving process is "The solvent molecules surround the solute particles".
Shaking affects the rate at which a solute dissolves because it increases the molecular activity of the solute within the solvent. When the molecular activity is increased, the rate of dissolving is also increased.
Solvent
when solute is dissolved in a solvent...the molecules of the solute starts diffusing between the particles of the solute.

In a basic saltwater solution, the water molecules would be the solvent and the salt molecules would be the solute.
