Assuming this reaction is occurring in aqueous solution:

#Na_2SO_4(aq) + CaCl_2(aq) to 2NaCl(aq) + CaSO_4(s)#

Calcium sulphate has poor solubility in aqueous solution. Hence, only #NaCl# will measurably dissociate. #CaSO_4# will precipitate in a significant amount d/t its low #K_(sp)# (#2.4*10^-5#).
