What does dissolving a solute and filtering a solution do?
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.
