The equation 2K2SO4 -> 2K + 2SO2 + O2

  1. Detailed information about the equation 2K2SO4 -> 2K + 2SO2 + O2 ->
    This equation describes the decomposition process of potassium sulfate (K2SO4) into potassium (K), sulfur dioxide (SO2), and oxygen (O2). The equation is balanced, meaning each element appears with the same number of atoms on both sides of the equation.

  2. Reaction conditions
    This reaction requires a high temperature such as the melting point of K2SO4 (1069°C). In addition, the reaction also requires the presence of a catalyst to speed up the reaction.

  3. Reaction Process
    When the temperature is high enough, K2SO4 begins to decompose. Potassium will separate and evaporate due to its low boiling point (774°C), while the oxygen and sulfur atoms combine to form sulfur dioxide (SO2). The reaction process continues until either K2SO4 is used up or the stopping conditions are met.

  4. Phenomena occurring
    During the reaction process, observers can see the color of the mixture changing. Potassium is shiny silver, while K2SO4 is white or colorless. When the reaction occurs, the color of the mixture may turn pale yellow due to the appearance of SO2. Additionally, the release of gas can be detected when O2 separates and evaporates.
