The equation 8HNO3 + 3Cu -> 3Cu(NO3)2 + 4H2O + 6NO

  1. Detailed information about the chemical equation:
    This is a chemical equation representing the reaction process between nitric acid (HNO3) and copper (Cu) to produce Copper II Nitrate (Cu(NO3)2), water (H2O), and Nitric oxide (NO).
  • The left (reactant) side of the equation includes 8 moles of nitric acid and 3 moles of copper.
  • The right side (product) consists of 3 moles of Copper II Nitrate, 4 moles of water, and 6 moles of Nitric Oxide.

  1. Reaction conditions:
    The reactants need to have direct contact with each other. The reaction usually takes place at room temperature. However, the reaction rate can increase if the temperature rises.

  2. Reaction process:
    Copper reacts with nitric acid to create Copper II Nitrate, water, and Nitric oxide.

  3. Phenomena observed:
    When copper reacts with nitric acid, there are phenomena of boiling, characteristic smoke emission and the color of the solution changes from blue to green. Additionally, it also produces Nitric Oxide (NO), a reddish-brown gas.
