The net ionic equation for the reaction of calcium sulfite with nitric acid is a. CaSO 3(s) + 2HNO 3(aq) → Ca 2+(aq) + 2NO 3 –(aq) + SO 2(g) + H 2O( ). b. Ca(HSO 3) 2(s) + 2HNO 3(aq) → Ca 2+(aq) + 2NO 3 –(aq) + SO 2(g) + 2H 2O( ). c. CaSO 3(s) + 2HNO 2(aq) → Ca 2+(aq) + 2NO 2 –(aq) + SO 2(g) + H 2O( ). d. CaSO 3(s) + 2H +(aq) → Ca 2+(aq) + SO 2(g) + H 2O( ). e. Ca 2+(aq) + CO 3 2–(aq) + 2H +(aq) + 2NO 3 –(aq) → Ca(NO 3) 2(aq) + SO 2(g) + H 2O( ).
