The chemical reaction Ba(NO3)2 + Na2CO3 -> BaCO3 + 2NaNO3

  1. Detailed information about the equation Ba(NO3)2 + Na2CO3 -> BaCO3 + 2NaNO3
  • This equation represents the ion exchange reaction between barium nitrate (Ba(NO3)2) and sodium carbonate (Na2CO3) to form barium carbonate (BaCO3) and sodium nitrate (NaNO3).
  • The barium carbonate formed is a solid insoluble in water and will precipitate to the bottom. The sodium nitrate formed is soluble in water.
  1. Reaction conditions
  • This reaction usually occurs at room temperature.
  • Both reactants, barium nitrate and sodium carbonate, need to be dissolved in water to allow ions to move and react with each other.
  1. Reaction process
  • Step 1: Barium nitrate and sodium carbonate dissolve in water, forming free ions: Ba2+ ions, NO3- ions, Na+ ions, and CO3 2- ions.
  • Step 2: Ba2+ ions and CO3 2- ions combine to form the precipitate compound, barium carbonate.
  • Step 3: The reaction continues until one of the original reactants is completely consumed, forming the final products of barium carbonate and sodium nitrate.
  1. Phenomena occurred
  • When the solutions of barium nitrate and sodium carbonate are mixed together, the white precipitate of barium carbonate can be observed.
  • The solution after the reaction contains sodium nitrate, this substance does not cause changes in color or precipitation.
