How to write an equation to show dissociation?

Drain cleaner is typically a solution of sodium hydroxide. Some antacids major component is
magnesium hydroxide. Write equations to show the dissociation of each base when placed into water.

Answer:

Please refer to the explanation below.

Explanation:

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

For an aqueous solution of sodium hydroxide, we have

#NaOH(aq)rightleftharpoonsNa^+(aq)+OH^(-)(aq)#

While for magnesium hydroxide, we got:

#Mg(OH)_2(aq)rightleftharpoonsMg^(2+)(aq)+2OH^(-)(aq)#

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.
