Identify the reactants: Barium nitrate (Ba(NO3)2) and potassium carbonate (K2CO3).
Write the balanced chemical equation for the reaction: Ba(NO3)2 (aq) + K2CO3 (aq) → BaCO3 (s) + 2 KNO3 (aq).
Determine the solubility of the products: Barium carbonate (BaCO3) is insoluble in water and will precipitate, while potassium nitrate (KNO3) is soluble.
Identify the precipitate: The insoluble compound that forms is barium carbonate (BaCO3).
Conclude that the name of the compound that precipitates is barium carbonate.
