The equation 6HNO3 + 3CuS -> 3Cu(NO3)2 + 3H2O + 3NO + 3SO2

  1. Detailed information about the equation 6HNO3 + 3CuS -> 3Cu(NO3)2 + 3H2O + 3NO + 3SO2
  • This equation describes the reaction between Nitric acid (HNO3) and copper sulfide (CuS) to form copper (II) nitrate (Cu(NO3)2), water (H2O), nitrogen monoxide (NO) and sulfur dioxide (SO2).
  1. Reaction conditions
  • The reaction occurs when the two reactants come into contact with each other and there is enough temperature to stimulate the reaction.
  1. Reaction Process
  • When Nitric acid (HNO3) comes into contact with copper sulfide (CuS), it reacts to form copper (II) nitrate (Cu(NO3)2), water (H2O), nitrogen monoxide (NO) and sulfur dioxide (SO2).
  1. Occurring phenomenon
  • When the reaction occurs, we can observe the formation of products along with the release of heat. The color of the mixture will change according to the formation of the products. Specifically, copper (II) nitrate will have a light blue color, nitrogen monoxide gas is yellow and sulfur dioxide gas is light yellow.
