As a chemical expert with a focus on organic chemistry, I'm delighted to delve into the reactions of citric acid, a weak organic acid found widely in citrus fruits. Citric acid, with the chemical formula \( \text{C}_6\text{H}_8\text{O}_7 \), is a tricarboxylic acid that can participate in a variety of chemical reactions due to its multiple functional groups.
Acid-Base Reactions: Citric acid, being an acid, reacts with bases to form salts and water. This is a neutralization reaction. For instance, when citric acid reacts with sodium bicarbonate, commonly known as baking soda, it forms sodium citrate, carbon dioxide, and water. The reaction can be represented as follows:
\[ \text{C}_6\text{H}_8\text{O}_7 + 3\text{NaHCO}_3 \rightarrow \text{C}_6\text{H}_5\text{Na}_3\text{O}_7 + 3\text{CO}_2 + 3\text{H}_2\text{O} \]
Complexation Reactions: Citric acid has the ability to chelate metal ions due to its multiple carboxylic acid groups. It forms complexes with metal ions such as iron, calcium, and magnesium, which can be useful in various industrial applications, including food preservation and pharmaceuticals.
Esterification Reactions: Citric acid can react with alcohols to form esters. This is an esterification process that can be catalyzed by acids and is reversible.
Decarboxylation Reactions: Under certain conditions, citric acid can undergo decarboxylation, a process where a carboxyl group is removed from a molecule, releasing carbon dioxide and forming a different compound.
Oxidation Reactions: Citric acid can be oxidized to form compounds like citramalic acid or even further oxidized to oxalic acid, depending on the reaction conditions and the oxidizing agent used.
Hydrolysis Reactions: Although citric acid is already in its acid form, it can still participate in hydrolysis reactions when it forms esters, which can be hydrolyzed back to citric acid and the corresponding alcohol.
The reaction with baking soda that you mentioned is particularly interesting because it's a common example of a reaction that produces carbon dioxide gas, which is not only a normal component of our atmosphere but also a key ingredient in carbonated beverages and a gas that we exhale naturally. This reaction is often used in cooking and baking to create a leavening effect, where the carbon dioxide gas forms bubbles that cause the dough to rise.
Citric acid's versatility in reactions is a testament to its importance in various fields, from food and beverage to pharmaceuticals and beyond. Its ability to participate in acid-base reactions, complexation, esterification, decarboxylation, oxidation, and hydrolysis makes it a valuable compound with a wide range of applications.

When citric acid and baking soda react with one another, they change chemi- cally and form sodium ions, citric acid ions, carbon dioxide gas, and water. Carbon dioxide gas is a normal component in our air. It also makes up the bubbles in carbonated drinks and is a gas we naturally exhale.
