The chemical equation 6HNO3 + 2Cu2S -> 4NO2 + 2H2O + 2Cu(NO3)2 + 2S

  1. Detailed information about the equation 6HNO3 + 2Cu2S -> 4NO2 + 2H2O + 2Cu(NO3)2 + 2S

    • The above chemical equation describes the reaction process between Nitric acid (HNO3) and Copper sulfide (Cu2S) to produce Nitrogen dioxide (NO2), water (H2O), Copper nitrate (Cu(NO3)2), and sulfur (S).

  2. Reaction conditions

    • The conditions for this reaction typically occur at room temperature.

  3. Reaction Process

    • The reaction process takes place when the two substances HNO3 and Cu2S come into contact with each other. The molecules HNO3 and Cu2S begin to react, producing products such as NO2, H2O, Cu(NO3)2, and S.

  4. Phenomena occurring

    • When the reaction process takes place, you will see the phenomenon of brown NO2 gas being released. Black copper sulfide (Cu2S) will gradually disappear and a blue-blue-green solid, copper nitrate (Cu(NO3)2), will appear. The sulfur (S) produced in the reaction process will be a yellow solid.
