Final answer:
The net ionic equation for the reaction between potassium hydrogencarbonate (KHCO3) and sulfuric acid (H2SO4) is HCO3-(aq) + H+(aq) → CO2(g) + H2O(l). Potassium ions are spectator ions and are not included in the net ionic equation.
Step-by-step explanation:
Net Ionic Equation for Potassium Hydrogencarbonate and Sulfuric Acid
When potassium hydrogencarbonate (KHCO3) reacts with sulfuric acid (H2SO4), a double displacement reaction occurs, and the products are potassium sulfate (K2SO4), carbon dioxide (CO2), and water (H2O). The balanced chemical reaction is:
KHCO3(s) + H2SO4(l) → K2SO4(aq) + 2CO2(g) + 2H2O(l)
To write the net ionic equation, we need to include only the species that undergo a chemical change. Ions that appear unchanged on both sides of the equation are called spectator ions and are therefore not included in the net ionic equation. Potassium ions (K+) do not undergo a chemical change and hence are spectators. The resulting net ionic equation is:
HCO3−(aq) + H+(aq) → CO2(g) + H2O(l)
