- 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.
- Reaction conditions:
- Both reactants dissolve in water, so the solvent needed is water.
- The common reaction temperature is room temperature.
- 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.
- 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.
