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?
dissociation
What is the difference between mouth dissolving and fast dissolving tablet?
"Orally disintegrating" and "mouth dissolving" both mean the same and are just flash names given to orally dissolvable tablets by drug companies.
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.
The destinguish between bond dissociation energy and atomization energy?
If you product has for example, dissociation of chlorine, it will have 2 atoms of chlorine in atomization, 0.5chlorine on balancing will give you only 1 mole of chlorine atom not 2 moles of atoms like dissociation enthalpy.
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 process of sodium chloride dissolving in water?
dissociation
The process whereby water molecules surround ions during the process of dissolving is called?
dissociation
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 reacting?
dissolving is when a substance dissapears and reacting is when it REACTS to what you mixed together
What is the difference between dissolving and annuling a marriage?
Dissolving is the same as divorcing. Annulling indicates the marriage was not consummated.
What the difference between dissociation and solvation?
Dissociation is when a person's conscious s completely or partially disrupted. Solvation is when the molecules become attracted within a solvent or solute.
What is the term for the process of an ionic compound dissolving in water and separating into positive and negative ions?
dissociation
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 mouth dissolving and fast dissolving tablet?
"Orally disintegrating" and "mouth dissolving" both mean the same and are just flash names given to orally dissolvable tablets by drug companies.
What makes an acid stronger than the other?
The difference is between dissociation constants. A high value has the meaning of strong acid.
What is the difference between melting vs dissolving?
melting is when an object chemicaly changes.. dissolving is when the object well... dissolves... if you need the exact definition of dissolve go to wikiapedia BaYmAr
What is the difference between melting and dissolving particles?
To melt is to go from solid form to a liquid state. To dissolve is to disintegrate, or terminate.
