The chemical equation is Ba(NO3)2 + KOH -> Ba(OH)2 + 2KNO3.

  1. Detailed information about the equation Ba(NO3)2 + KOH -> Ba(OH)2 + 2KNO3:
  • Ba(NO3)2: Barium nitrate, a white, odorless solid that dissolves well in water.
  • KOH: Potassium hydroxide, a white, odorless solid that dissolves well in water.
  • Ba(OH)2: Barium hydroxide, a white, odorless solid that dissolves well in water.
  • KNO3: Potassium nitrate, a white, odorless solid that dissolves well in water.
  1. Reaction conditions:
  • Both reactants dissolve in water, so the solvent needed is water.
  • The common reaction temperature is room temperature.
  1. Reaction process:
  • This reaction is an ion exchange reaction between barium nitrate and potassium hydroxide to form barium hydroxide and potassium nitrate.
  • In the solution, Ba(NO3)2 and KOH will dissociate into separate ions. Then, the Ba2+ ion will combine with the OH- ion to form Ba(OH)2; the K+ ion will combine with the NO3- ion to form KNO3.
  1. Phenomena occurred:
  • When the two reactants are mixed together in solution, a precipitation of barium hydroxide will appear. This precipitate is white and does not dissolve in water.
