Write a balanced reaction for the gas release reaction of AlkaSeltzer, sodium bicarbonate with citric acid, $\mathrm{C}_{6} \mathrm{H}_{8} \mathrm{O}_{7}$. (The acid is a triprotic acid and consists of a chain of three carbon atoms, each with a carboxylic acid group, COOH.)

Key Concepts

Acid-Base Neutralization

Acid-base neutralization is a fundamental chemical reaction where an acid reacts with a base to produce a salt and water, with the reaction often driven to completion by the formation of a gaseous product. This process involves the transfer of protons and the formation of conjugate acid-base pairs, typically resulting in a neutralization of the reactive components.

Triprotic Acid Characteristic

A triprotic acid is capable of donating three protons, which significantly influences the stoichiometry of its reactions with bases. Each acidic proton can react with a base, so understanding this characteristic is key to determining the correct molar ratios required for complete neutralization in balanced chemical equations.

Gas Evolution Reaction

A gas evolution reaction is characterized by the formation of a gaseous product as a result of the chemical reaction. This type of reaction is common in acid-base processes where, upon neutralization, a gas, such as carbon dioxide, is released, thereby shifting the reaction equilibrium and serving as a visual indicator of reaction progress.

Stoichiometry and Balancing Chemical Equations

Stoichiometry involves quantifying the relationships between reactants and products in a chemical reaction to ensure the law of conservation of mass is met. Balancing chemical equations requires adjusting the coefficients of reactants and products so that the number of atoms for each element, as well as the overall charge, is equal on both sides of the equation, providing a precise description of the reaction's progress.
