The chemical equation Cu + 2H2SO4 -> CuSO4 + 2H2O + SO2

  1. Detailed information about the equation Cu + 2H2SO4 -> CuSO4 + 2H2O + SO2:
  • According to the equation, one mole of copper (Cu) will react with two moles of sulfuric acid (H2SO4) to produce one mole of copper (II) sulfate (CuSO4), two moles of water (H2O), and one mole of sulfur dioxide (SO2).
  1. Reaction conditions:
  • The reaction occurs when copper is in contact with diluted or concentrated sulfuric acid at room temperature or higher.
  1. Reaction process:
  • When copper is added to a solution of sulfuric acid, it reacts with the acid to form copper (II) sulfate, water, and sulfur dioxide.
  1. Occurring phenomena:
  • When the reaction occurs, you can see the disappearance of the red color of copper and the emergence of the blue color of copper (II) sulfate.
  • There may be the development of gas bubbles, which are sulfur dioxide (SO2) escaping.
  • If the reaction takes place at high temperature, white smoke may be seen due to the condensation of water vapor and sulfur dioxide.
