What are some examples of solubility equilibria?

1 Answer

NaCl(s) #rightleftharpoons# NaCl(aq)

or

NaCl #rightleftharpoons# #Na^+#(aq) + #Cl^-#(aq)

When enough salt has been added to create a saturated solution and then additional salt is added, there is a dynamic equilibrium between the dissolving of salt and the crystallization of salt.

The video below gives further explanation and lets you see what is happening at the particle level:
