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 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 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.
How do the processes of dissolution and dissociation differ in terms of their effects on chemical compounds?
Dissolution is the process of a solid substance dissolving into a liquid, while dissociation is the breaking apart of a compound into its individual ions in a solution. Dissolution affects the physical state of a substance, while dissociation changes its chemical composition.
Is salt dissolving a chemical reaction?
Yes. A salt is an ionic compound and so dissolving (or hydrolyzing) it is a chemical reaction. An example with sodium chloride (table salt): NaCl (solid) -> Na+ + Cl- The charges on the products indicate that they are aqueous (in solution). Since the reactant breaks apart into it's products, this is a dissociation reaction.

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.

Is dissolving air in water a chemical change?
It is a physical change, and now you have a mixture (or solution). No chemical reactions took place to make this change.
Is coffee dissolving in water a physical or chemical change?
It is a physical change. Dissolving is a physical property called solubility.
What is chemical reaction associated with energy change?
Chemical reactions that release energy are exothermic, such as combustion reactions where energy is released in the form of heat and light. Conversely, endothermic reactions absorb energy from the surroundings, like the dissociation of ammonium chloride in water.
