The chemical equation 8HNO3 + 3Cu2S -> 3Cu(NO3)2 + 4H2O + 6NO + 2SO2

  1. Detailed Information about the Equation 8HNO3 + 3Cu2S -> 3Cu(NO3)2 + 4H2O + 6NO + 2SO2

The above chemical equation describes the reaction process between nitric acid (HNO3) and copper (I) sulfide (Cu2S), resulting in the formation of copper (II) nitrate (Cu(NO3)2), water (H2O), nitric oxide (NO), and sulfur dioxide (SO2).

  1. Reaction Conditions

This reaction takes place under standard temperature and pressure conditions. It requires the presence of a catalyst to accelerate the reaction rate.

  1. Reaction Process

When nitric acid and copper (I) sulfide are mixed together, they react to form copper (II) nitrate, water, nitric oxide, and sulfur dioxide. This reaction is a redox reaction, with copper (I) sulfide being oxidized to copper (II) nitrate and nitric acid being reduced to nitric oxide.

  1. Occurring Phenomena

When the reaction takes place, you will notice a color change as copper (II) nitrate is formed. Additionally, you will also observe the release of nitric oxide and sulfur dioxide gases.
