Please refer to the explanation below.


I would say we can write the following equations like this.

For an aqueous solution of sodium hydroxide, we have


While for magnesium hydroxide, we got:


Remember that dissociation reactions are usually reversible, so I would suggest that it is safe to place the equilibrium #(rightleftharpoons)# sign in the chemical equations.
