Question

What is the net ionic equation of 2h+ + so42- + ca2+ + 2i- caso4 + 2h+ + 2i-?

Answer 1

he is right he is correct

Answer 2

What  is  the  net  ionic equation
2 H^+  + SO4^2-  + Ca^2+  +  2 i^- = CaSo4  + 2H^+  +2i ^-
cancel  the spectator  ion that is the  ions  which  does  not take  place  nin  the  reaction

for this  case  is  2 H^+  and 2 i^-

the net ionic equation  is  therefore
=Ca^2+  + SO4^2- = CaSO4
