![**Net Ionic Equation for Formation of Aqueous NiI2 and CO2 Evolution**
**Question:**
The net ionic equation for the formation of an aqueous solution of NiI2 accompanied by the evolution of CO2 gas via mixing solid NiCO3 and aqueous hydroiodic acid is ________.
**Options:**
A) 2NiCO3(s) + HI(aq) → 2H2O(l) + CO2(g) + 2Ni2+(aq)
B) NiCO3(s) + I-(aq) → 2H2O(l) + CO2(g) + Ni2+(aq) + HI(aq)
C) NiCO3(s) + 2H+(aq) → H2O(l) + CO2(g) + Ni2+(aq)
D) NiCO3(s) + 2HI(aq) → 2H2O(l) + CO2(g) + NiI2(aq)
E) NiCO3(s) + 2HI(aq) → H2O (l) + CO2(g) + NiI2(aq) + I2-(aq)
**Correct Answer: C**
**Explanation:**
The correct net ionic equation represents the reaction of nickel(II) carbonate (NiCO3) with hydrogen ions (H+) from hydroiodic acid (HI), resulting in the formation of water (H2O), carbon dioxide (CO2), and nickel(II) ions (Ni2+). The H+ ions originate from the dissociation of HI in aqueous solution, but the iodine ions (I-) are spectator ions and do not participate in the net ionic equation.
**Details of the Reaction:**
- Nickel(II) carbonate (NiCO3) is a solid reactant.
- Hydroiodic acid (HI), which provides H+ ions in aqueous solution.
- The primary products include water (H2O in liquid state), carbon dioxide (CO2 in gaseous form), and nickel(II) ions in aqueous solution (Ni2+(aq)).
This reaction highlights the typical process of a carbonate reacting with an acid to produce water and carbon dioxide, alongside the soluble nickel ions in the aqueous phase.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcae570f7-e718-48ae-a7f5-23141fe5c1a2%2F2432a5c8-77ed-4f9e-b895-f4cf705e2949%2Fhd8a9ob_processed.png&w=3840&q=75)
