If an antacid has sodium hydrogen carbonate/Calcium carbonate, it reacts with HCl as shown

NaHCO₃ + HCl → NaCl + CO₂ + H₂O

Antacid acid salt gas water

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

Antacid acid salt gas water

The formation of gas CO₂ is shown by brisk effervescence when the antacid (sodium hydrogen carbonate/calcium carbonate) reacts with HCl (acid). So CO₂ is the additional product formed and its formation is supported by observation of brisk effervescence as HCl is added to the antacid.
