Here are the essential concepts you must grasp in order to answer the question correctly.
Chemical Reaction
The foaming and bubbling of Alka-Seltzer when dissolved in water is a result of a chemical reaction between its ingredients, primarily sodium bicarbonate and citric acid. When these two compounds come into contact with water, they react to produce carbon dioxide gas, which forms bubbles and creates the characteristic fizzing effect.

Antacid Function
Alka-Seltzer contains sodium bicarbonate, which acts as the active antacid ingredient. Antacids neutralize stomach acid, providing relief from heartburn and indigestion by increasing the pH level in the stomach, thus alleviating discomfort caused by excess acidity.

Dissolution Process
The dissolution process refers to how solid substances, like the components of Alka-Seltzer, interact with water to form a solution. In this case, the dissolution of the tablet allows the reactants to mix and react, leading to the production of gas and the visible foaming effect, which is a key aspect of the product's functionality.
