The chemical equation KHCO3 + 2H2SO4 -> K2SO4 + 2H2O + 2CO2

  1. Detailed information about the chemical equation KHCO3 + 2H2SO4 -> K2SO4 + 2H2O + 2CO2:

    • The above chemical equation illustrates the reaction process between potassium bicarbonate (KHCO3) and sulfuric acid (H2SO4) to produce potassium sulfate (K2SO4), water (H2O), and carbon dioxide gas (CO2).
    • According to the law of conservation of elements, each type of element on both sides of the chemical equation must balance, meaning the number of moles of each element on both sides of the equation must be equal. In the above equation, all elements are conserved.

  2. Reaction conditions:

    • The reaction occurs under normal temperature conditions.

  3. Reaction process:

    • Initially, potassium bicarbonate (KHCO3) and sulfuric acid (H2SO4) react with each other to form potassium sulfate (K2SO4), water (H2O), and carbon dioxide gas (CO2) is released.
    • This process occurs through an ion exchange reaction.

  4. Observed phenomena:

    • When KHCO3 is introduced into the H2SO4 solution, bubbling occurs due to the release of CO2 gas.
