The equation Zn + H2SO3 -> ZnSO3 + H2

  1. Detailed information about the reaction Zn + H2SO3 -> ZnSO3 + H2

    • The above equation represents the chemical reaction process between zinc metal (Zn) and sulfurous acid (H2SO3) to form ZnSO3 (zinc sulfate) and hydrogen (H2).

  2. Reaction conditions

    • Conditions for the above reaction to occur require an acidic environment and appropriate temperature. In addition, the reaction also needs to be supplied with initial energy to start the process.

  3. Reaction process

    • During the reaction process, zinc will react with sulfurous acid, performing ion exchange to create zinc sulfate and hydrogen.

  4. Observed phenomena

    • When the reaction occurs, there will be a phenomenon of hydrogen gas bubbles escaping. If collected and burned, this hydrogen gas will produce a faint blue flame. The precipitated product, zinc sulfate, typically has a white color.
