Answer:
By converting the compound to the ionic form, ionic equation can be given.
Explanation:
Ionic equation for a reaction represents the change in ionic state of the elements involved in reaction.
The balanced ionic equation can be written when the number of ions for substrate and product for each element are equal.
The compounds are first breakdown into an ionic form for the ionic reaction:
[tex]\RM Na_2SO_4[/tex] can be ionically written as [tex]\rm 2\;Na^+[/tex]and [tex]\rm SO_4^2-[/tex].
Ionic form of [tex]\RM CaCl_2[/tex] is [tex]\rm Ca^2^+[/tex] and [tex]\rm 2\; Cl^-[/tex].
Ionic form of [tex]\rm CaSO_4[/tex] is [tex]\rm Ca^2^+[/tex] and [tex]\rm SO_4^2-[/tex].
Ionic form of NaCl is [tex]\rm Na^+[/tex] and [tex]\rm Cl^-[/tex].
The overall ionic equation will be:
[tex]\rm 2\; Na^+\; +\; SO_4^2^-\; +\;Ca^2^+\; +\; 2\;Cl^-\rightarrow\; Ca^2^+\; +\; SO_4^2^-\; +\; 2\;Na^+\; +\; 2\;Cl^-[/tex].
