The equation Ca(NO3)2 + Ba(OH)2 -> Ba(NO3)2 + Ca(OH)2

  1. Detailed information about the equation Ca(NO3)2 + Ba(OH)2 -> Ba(NO3)2 + Ca(OH)2:

    • The above chemical equation represents the ion exchange reaction between calcium nitrate (Ca(NO3)2) and barium hydroxide (Ba(OH)2) to form barium nitrate (Ba(NO3)2) and calcium hydroxide (Ca(OH)2).
    • Specifically, the ion exchange reaction occurs when there is simultaneous movement of anions (NO3- from Ca(NO3)2 to Ba(OH)2) and cations (Ca2+ from Ca(NO3)2 to Ba(OH)2) from one substance to another.

  2. Reaction conditions:

    • The reaction takes place under standard temperature and pressure conditions.
    • Both reactants must be in ion form in solution.

  3. Reaction Process:

    • Initially, calcium nitrate and barium hydroxide are in ion form in solution.
    • When these two solutions are mixed together, the Ba2+ ion from barium hydroxide combines with the NO3- ion from calcium nitrate to form barium nitrate.
    • Simultaneously, the Ca2+ ion from calcium nitrate combines with the OH- ion from barium hydroxide to form calcium hydroxide.

  4. Observed phenomena:

    • When the two reacting solutions are mixed together, a precipitation phenomenon will occur. This white precipitate is calcium hydroxide.
    • Meanwhile, barium nitrate remains soluble in solution.
