Answer: hydrochloric acid solution.
Explanation of the solution to the problem: under the action of hydrochloric acid (HCl) on carbonate ion (СО3 (2-)), chloride ion (Cl (-)) and carbonic acid (Н2СО3) are formed, which is a very unstable acid and decomposes into water in an aqueous solution (H2O) and carbon dioxide (CO2). Visually, this becomes noticeable, because colorless bubbles of carbon dioxide begin to appear in the solution, this sign helps to detect the presence of carbonate ions in the solution.
