What is a dissolution with reaction?

1 Answer

Answer:

Dissolution is the process by which a solute forms a solution in a solvent

Explanation:

Dissolution Reactions:

  • Nonelectrolytes:

When a nonelectrolyte dissolves into solute it changes from its original state (the solid or liquid or gas phase) and goes into solution becoming aqueous.

Example, alcohol

#C_2H_5OH_(l) -> C_2H_5OH_(aq)#

  • Strong Electrolytes

In the case of a strong electrolyte(solid, liquid, or gas) it goes into solution and is ionized in the process.

Example, sodium chloride

#NaCl_((s)) -> Na_((aq))^(+) + Cl_((aq))^(-)#

  • Weak Electrolytes

When a weak electrolyte dissolves in water (solid, liquid, or gas) Some, not all, but some of those molecules dissociate into ions. Those ions in turn reassociate to form the molecules.

An equilibrium is set up where the molecules are dissociating just as fast as the ions are recombining to form molecules.

Example, acetic acid

#C_2H_3O_2H_((l)) rightleftharpoons C_2H_3O_2H_((aq)) rightleftharpoons C_2H_3O_(2(aq))^(-) + H_((aq))^+#

The double arrow indicates that this is an equilibrium reaction
