When ionic compounds (compounds made from metals and non-metals) like sodium chloride ##"NaCl"## or iron(III) sulfate ##"Fe"_2("SO"_4)_3## are dissolved in water, they come apart into positive (metal) ions and negative (non-metal) ions.
When you write a dissociation reaction you separate the two ions, place their charges above their symbols, and then balance the entire equation.
For example, the dissociation of sodium chloride would look like this:
##"NaCl" → "Na"^+ + "Cl"^-##
The dissociation of iron(III) sulfate would look like this:
##"Fe"_2("SO"_4)_3 → 2"Fe"^(3+) + 3"SO"_4^(2-)##
