The equation Cu2O + 2HNO3 -> 2Cu(NO3)2 + H2O.

  1. Detailed information about the equation Cu2O + 2HNO3 -> 2Cu(NO3)2 + H2O

The above equation describes the reaction between copper(I) oxide (Cu2O) and nitric acid (HNO3), resulting in copper(II) nitrate (Cu(NO3)2) and water (H2O).

  1. Reaction conditions

This reaction occurs when Cu2O comes in contact with HNO3. The specific conditions may depend on the concentration of HNO3, but typically do not require specific temperature or pressure.

  1. Reaction process

Cu2O reacts with HNO3 to form Cu(NO3)2, this compound then reacts with additional HNO3 to produce another Cu(NO3)2 and H2O. This results in two molecules of Cu(NO3)2 from each molecule of Cu2O.

  1. Phenomena occurring

When Cu2O reacts with HNO3, a color change can be observed from the red of Cu2O to the blue of Cu(NO3)2. There may be an increase in temperature due to the reaction between Cu2O and HNO3.
