The chemical equation Cu + HNO3 + H2O2 -> Cu(NO3)2 + H2O.

  1. Detailed Information about the Reaction Cu + HNO3 + H2O2 -> Cu(NO3)2 + H2O

The above chemical equation describes the reaction process between Copper (Cu), Nitric Acid (HNO3), and Hydrogen Peroxide (H2O2), which results in the formation of Copper Nitrate (Cu(NO3)2) and water (H2O).

  1. Reaction Conditions

The reaction occurs when Copper, Nitric Acid, and Hydrogen Peroxide are combined. Temperature and pressure do not significantly impact the progression of the reaction. Nitric Acid needs to be of a sufficient concentration to oxidize the Copper. Hydrogen Peroxide acts as a strong oxidizer, helping the reaction occur more rapidly.

  1. Reaction Process

The reaction process consists of two main stages:

  • Copper reacts with Nitric Acid to create Copper Nitrate (II).
  • Copper Nitrate (II) continues to react with Hydrogen Peroxide to produce water.
  1. Occurring Phenomena

When Copper reacts with Nitric Acid and Hydrogen Peroxide, the following phenomena occur:

  • The initial blue color of the Copper gradually changes to green, and finally to the dark blue color of Copper Nitrate (II).
  • There is effervescence (if the temperature is high enough) and heat is produced, indicating that a chemical reaction is taking place.
  • Finally, a special liquid (water) is produced from the reaction process.
