In the CO2 absorber, CO2 chemically combines with water to form which compound?

Explanation:
When CO2 dissolves in water, it undergoes hydration to form carbonic acid (H2CO3). This weak acid partially dissociates to bicarbonate (HCO3−) and hydrogen ions, which is why CO2 in solution behaves as a carbonic acid–bicarbonate system. The other acids listed are not produced by CO2 reacting with water.
