To take the tablets, they should be fully dissolved in a glass of water. The pain reliever used is aspirin and the antacid used is baking soda (sodium bicarbonate, NaHCO 3). However, with Alka-Seltzer, the CO 2 is produced by a chemical reaction that occurs when the tablets dissolve in water.Īlka-Seltzer is a medical drug that works as a pain reliever and an antacid (antacids help neutralize stomach acidity, such as heartburn). And like a soda, the bubbles are carbon dioxide gas (CO 2). You may have seen a television commercial for Alka-Seltzer tablets or heard one of their advertising slogans: “Plop, plop, fizz, fizz, oh what a relief it is!” When you drop the tablets in water, they make a lot of bubbles, like an extra-fizzy soda, as shown in the main image up top (Figure 1).
