Acids also play a significant role in mining operations. Sulfuric acid is extensively used in the hydrometallurgical processing of metals such as copper and nickel. In copper leaching, for instance, sulfuric acid is employed to dissolve copper from its ore in a process called heap leaching. While effective, the use of acids raises concerns regarding acid mine drainage—a phenomenon where acid and heavy metals leach into the environment, impacting local ecosystems and water quality. Consequently, mining companies are increasingly adopting techniques to neutralize acid production and treat contaminated water.

Food additives can be categorized into several groups, including preservatives, flavor enhancers, colorings, and stabilizers. Preservatives, such as sodium benzoate and sulfur dioxide, are used to inhibit the growth of harmful bacteria, molds, and yeasts, thereby prolonging the shelf life of perishable products. This is particularly important in a global market where food is transported over long distances and needs to remain safe and consumable for extended periods.

One of the most well-known uses of sodium bicarbonate in food is as a leavening agent. When combined with an acid—such as vinegar, lemon juice, or buttermilk—sodium bicarbonate undergoes a chemical reaction that produces carbon dioxide gas. This gas forms bubbles in batters and doughs, causing them to rise and resulting in a light, airy texture in baked goods such as cakes, muffins, and cookies. The versatility of sodium bicarbonate as a leavening agent is unparalleled, allowing for the creation of a wide variety of baked products with desirable textures.

Sodium bicarbonate is also an excellent cleaning agent due to its mild abrasiveness and alkaline nature. It can be used to scrub surfaces, deodorize, and even unclog drains when mixed with vinegar. Its non-toxic properties make it a popular choice among environmentally conscious individuals looking to avoid harsh chemicals in their homes. A paste made from sodium bicarbonate and water can be applied to stubborn stains, making it an effective option for cleaning dirty pots, pans, and countertops.
