The equation KHCO3 + 2HCl -> 2KCl + 2H2O + 2CO2

  1. Detailed information about the equation KHCO3 + 2HCl -> 2KCl + 2H2O + 2CO2:
  • The chemical equation above describes the reaction process between potassium bicarbonate (KHCO3) and hydrochloric acid (HCl) to produce potassium chloride (KCl), water (H2O), and carbon dioxide gas (CO2).
  • This is an acid-base displacement reaction, in which the acid (HCl) replaces the hydrogen in the base (KHCO3) to form a salt (KCl) and water (H2O), while also generating CO2 gas.
  1. Reaction conditions:
  • The standard conditions for this reaction are at room temperature and a pressure of 1 atm.
  1. Reaction process:
  • During the reaction process, the H+ ion from HCl acid will replace the H+ ion in the KHCO3 base to form K+ and Cl- ions, which results in the formation of KCl salt.
  • Simultaneously, the H+ ion from HCl acid will combine with the CO3– ion of the KHCO3 base to produce H2O and CO2.
  1. Occurring phenomena:
  • When these two compounds react with each other, there will be a phenomenon of CO2 gas rising, creating gas bubbles in the solution. At the same time, the solution will also show particles of KCl salt.
