The equation MgO + 2HNO3 -> Mg(NO3)2 + H2O

  1. Detailed information about the chemical equation MgO + 2HNO3 -> Mg(NO3)2 + H2O:

    • This balanced chemical equation describes the reaction process between magnesium oxide (MgO) and nitric acid (HNO3) to produce magnesium nitrate (Mg(NO3)2) and water (H2O).
    • According to the ratio of the equation, one mol of MgO reacts with two mols of HNO3 to produce one mol of Mg(NO3)2 and one mol of H2O.

  2. Reaction Conditions:

    • The conditions for the reaction are that the nitric acid is strong enough and the temperature is appropriate to react with magnesium oxide.

  3. Reaction Process:

    • When magnesium oxide (MgO) meets nitric acid (HNO3), it produces magnesium nitrate (Mg(NO3)2) and water (H2O).
    • This reaction is of the acid-base type according to the general formula AB + CD -> AD + BC.

  4. Occurring Phenomena:

    • When MgO is added to the HNO3 solution, MgO will gradually dissolve and produce CO2 gas which escapes from the solution.
    • The visible phenomenon is the gradual disappearance of MgO particles and the release of gas.
