Dissociation can be viewed as a subsection of dissolving. Dissolving is a general term for when something is placed into a solution, and the substance breaks up to make it seem as if the substance is no longer present. This could mean that the original structure of crystals breaks into molecules. For example, IF a chunk of NaCl was placed in water and it broke up into small molecules of NaCl, the process WOULD be one of dissolving. However, that would not be one of dissociation. In order for the above example to be dissociation, NaCl would have to be broken up into Na+ and Cl- ions independent of each other. Dissociation is "the separation of ions that occurs when an ionic compound dissolves" (Modern Chemistry by Holt, Rinehart and Winston). Thus, dissociation is more specific than dissolving. According to the related link, anything that dissociates also dissolves, but not everything that dissolves can dissociate.

The process whereby water molecules surround ions during the process of dissolving is called?
The process whereby water molecules surround ions during the process of dissolving is called hydration. This occurs when water molecules interact with and surround the charged particles of an ionic compound, breaking the ionic bonds and allowing the compound to dissolve in water.
What is the difference between mouth dissolving and fast dissolving tablet?
Mouth dissolving tablets are designed to dissolve in the mouth within seconds without the need for water, making them convenient for patients who have difficulty swallowing. Fast dissolving tablets, on the other hand, may dissolve quickly in the stomach or upon contact with liquid, but they do not necessarily need to be placed in the mouth like mouth dissolving tablets.
How do you derive the dissociation of CaCl2.2H2O?
The dissociation of CaCl2.2H2O involves breaking the compound into its ions when dissolved in water. In this case, CaCl2.2H2O will dissociate into Ca2+, 2Cl-, and 2H2O molecules. The dissociation process is driven by the attraction between the ions and the polar water molecules, causing them to separate and form a solution.
What is the difference between melting and dissolving?
Dissolving is the chemical state in which melting is physical state but the difference is when you dissolve something some things can be brought back but when you melt some thing you are mostly likely not to bring it back to it's natural form
What is the relationship between enthalpy of atomisation of hydrogen and the bond dissociation enthalpy of the H-H bond?
the enthalpy of atomisation of hydrogen is equal and (in principle) identical to the bond dissociation enthalpy of the H-H bond. However, IF the first is measured by calorimetry and the second by spectrometry there might be a systematic difference.
What is the difference between dissociation and dissolving in terms of their effects on a substance's chemical structure?
Dissociation involves breaking apart into ions, while dissolving involves mixing with a solvent without changing the chemical structure.
What is the difference between dissolving and dissociation in the context of chemical reactions?
Dissolving refers to a physical process where a substance breaks down into smaller particles and mixes evenly with a solvent, like sugar dissolving in water. Dissociation, on the other hand, is a chemical process where compounds break apart into ions when dissolved in a solvent, like salt dissociating into sodium and chloride ions in water.
What is the difference between dissociation and dissolution in the context of chemical reactions?
In the context of chemical reactions, dissociation refers to the separation of a compound into its individual ions, while dissolution refers to the process of a solid substance dissolving into a liquid to form a solution. Dissociation involves breaking chemical bonds, while dissolution involves the physical mixing of substances.
What is the process of sodium chloride dissolving in water?
dissociation
What is the difference between dissolution and dissociation in the context of chemical reactions?
Dissolution refers to the process of a solid substance dissolving in a liquid to form a solution, while dissociation involves the separation of ions in a compound into individual ions in a solution. In dissolution, the substance remains intact but is surrounded by solvent molecules, whereas in dissociation, the compound breaks apart into its constituent ions.
Describe the particle attraction that occurs as sodium chloride dissolves in water?
Dissolving and dissociation involve the removal of the attraction between particles.
What is the difference between dissolving and annuling a marriage?
Dissolving is the same as divorcing. Annulling indicates the marriage was not consummated.
What is the difference between dissociation and dissolution?
Dissociation refers to the separation of components or elements, while dissolution refers to the breaking down or dispersal of a substance into smaller parts.
What is chemical change when dissolving?
1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.
What is the difference between the processes of dissolution and dissociation?
Dissolution is the process where a solid substance dissolves in a liquid to form a solution, while dissociation is the process where a compound breaks apart into its individual ions in a solution.
How do you differentiate between the processes of dissociation and dissolution in chemistry?
In chemistry, dissociation refers to the breaking apart of a compound into its individual ions, while dissolution refers to the process of a solid substance dissolving into a liquid to form a solution. Dissociation involves the separation of ions within a compound, while dissolution involves the mixing of a solid substance with a liquid to form a homogeneous mixture.
What makes an acid stronger than the other?
The difference is between dissociation constants. A high value has the meaning of strong acid.
