The equation Ca(NO3)2 + H2O -> Ca(OH)2 + 2HNO3

  1. Detailed information about the equation Ca(NO3)2 + H2O -> Ca(OH)2 + 2HNO3
    This equation describes the reaction process between calcium nitrate (Ca(NO3)2) and water (H2O) to produce calcium hydroxide (Ca(OH)2) and nitric acid (HNO3). In this process, calcium from calcium nitrate will combine with hydrogen and oxygen from water to create calcium hydroxide, while nitrate from calcium nitrate will combine with hydrogen and oxygen to produce nitric acid.

  2. Reaction conditions
    This reaction can occur at room temperature. However, increasing the temperature may help accelerate the reaction rate.

  3. Reaction process
    The reaction process occurs based on the ion exchange between calcium nitrate and water. The calcium ion (Ca2+) from calcium nitrate will combine with the hydroxide ion (OH-) from water to produce calcium hydroxide. At the same time, the nitrate ion (NO3-) from calcium nitrate will combine with the hydrogen ion (H+) from water to produce nitric acid.

  4. Observed phenomena
    When this reaction occurs, you can observe a change in the color of the solution, from the colorless of calcium nitrate and water to the dull white color of calcium hydroxide. At the same time, you may also perceive the characteristic smell of nitric acid.
