The equation Cu(NO3)2 + K2S -> CuS + 2KNO3

  1. Detailed information about the equation Cu(NO3)2 + K2S -> CuS + 2KNO3

    • The above chemical equation represents a chemical reaction between copper (II) nitrate (Cu(NO3)2) and potassium sulfide (K2S) to produce copper (II) sulfide (CuS) and potassium nitrate (2KNO3).

  2. Reaction conditions

    • The reaction usually occurs under normal temperature and pressure conditions and requires the presence of a solvent for the two reactants to fully react.

  3. Reaction process

    • During the reaction process, copper (II) nitrate and potassium sulfide interact with each other, with the shifting of nitrate and sulfide ions, to form copper (II) sulfide and potassium nitrate.

  4. Phenomenon occurring

    • During the reaction process, a change in color can be observed from blue (the color of the copper (II) nitrate solution) to black (the color of copper (II) sulfide). Simultaneously, small particles of potassium nitrate are formed.
