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

  1. Detailed information about the chemical equation: The equation describes the reaction between quicklime (CaO) and nitric acid (HNO3), resulting in calcium nitrate (Ca(NO3)2) and water (H2O).

  2. Reaction conditions: The reaction occurs easily under standard temperature and pressure conditions. This is an acid-base reaction, so direct contact between the acid and base is required.

  3. Reaction process: When quicklime (CaO) comes into contact with nitric acid (HNO3), an acid-base reaction occurs, producing calcium nitrate (Ca(NO3)2) and water (H2O). This is an ion exchange reaction as both reactants are ions.

  4. Observed phenomena: When nitric acid is added to quicklime, a reaction occurs with heat being released, resulting in a solution of calcium nitrate and water. The specific phenomenon is the bubbling due to the reaction.
