Question

What is the net ionic equation of 2H+ + SO42- + Ca2+ + 2I- → CaSO4 + 2H+ + 2I-?

A. 2H+ + SO42- + Ca2+ → CaSO4 + 2H+
B. H2SO4(aq) + CaI2(aq) → CaSO4(s) + 2HI(aq)
C. SO42- + Ca2+ → CaSO4
D. H+ + SO42- + Ca2+ + 2I- → CaSO4 + H+ + 2I-

Answer 1

The net ionic equation is D) H+ + SO42- + Ca2+ + 2I- → CaSO4 + H+ + 2I-.

Step-by-step explanation:

The net ionic equation of the given reaction is option D:
H+ + SO42- + Ca2+ + 2I- → CaSO4 + H+ + 2I-

The net ionic equation represents the species that actually participate in the reaction, excluding spectator ions. In this case, the spectator ions are 2H+ and 2I-, which appear on both sides of the reaction. Therefore, they can be cancelled out to simplify the equation.

The resulting net ionic equation shows that Ca2+ reacts with SO42- to form CaSO4. The H+ and I- ions do not participate in the overall reaction and are therefore omitted from the equation.
