Carbonated water in the context of "Soft drink"

Mineral water is water from a mineral spring that contains various minerals, such as salts and sulfur compounds. It is usually still, but may be sparkling (carbonated/effervescent).

Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure", at places such as spas, baths and wells.

Bottled water is drinking water (e.g., well water, distilled water, reverse osmosis water, mineral water, or spring water) packaged in plastic or glass water bottles. Bottled water may be carbonated or not with packaging sizes ranging from small single-serving bottles to large carboys for water coolers. The consumption of bottled water is influenced by factors such as convenience, taste, perceived safety, and concerns over the quality of municipal tap water. Concerns about the environmental impact of bottled water, including the production and disposal of plastic bottles, have led to calls for more sustainable practices in the industry. Some brands have attempted to address the problem of microplastics and chemicals by canning purified water.

A carbonate is a salt of carbonic acid, (H₂CO₃), characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2−3. The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C(−O−)₂.

The term is also used as a verb, to describe carbonation: the process of raising the concentrations of carbonate and bicarbonate ions in water to produce carbonated water and other carbonated beverages – either by the addition of carbon dioxide gas under pressure or by dissolving carbonate or bicarbonate salts into the water.

Joseph Priestley FRS (/ˈpriːstli/; 24 March 1733 – 6 February 1804) was an English chemist, Unitarian, natural philosopher, separatist theologian, grammarian, multi-subject educator and classical liberal political theorist. He published over 150 works, and conducted experiments in several areas of science.

Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community.

Canned water is drinking water, including spring water, artesian spring water, purified water, carbonated water and mineral water, packaged in beverage cans made of aluminium or tin-plated steel.

Individual serving aluminium cans and bottles are less common alternatives to bottled water. Canned water is often used where storage or distribution systems are set up for cans. Some companies have launched water in cans, offering a more environmentally sustainable alternative to plastic bottles.

Pepsi is a carbonated soft drink with a cola flavor, manufactured by PepsiCo which serves as its flagship product. In 2023, Pepsi was the second most valuable soft drink brand worldwide behind Coca-Cola; the two share a long-standing rivalry in what has been called the "cola wars".

Pepsi, originally created in 1893 by Caleb Bradham and named "Brad's Drink," was first sold in his drugstore in New Bern, North Carolina. Renamed Pepsi-Cola in 1898 due to its supposed digestive benefits, its name was shortened to Pepsi in 1961. The beverage's formula initially included sugar and vanilla but not pepsin, despite speculation on the origin of its name. Early on, Pepsi struggled with financial stability, going bankrupt in 1923 but was subsequently purchased and revived by Charles Guth, who reformulated the syrup. Pepsi gained popularity with the introduction of a 12-ounce bottle during the Great Depression and clever marketing strategies like the "Nickel, Nickel" jingle, doubling sales by emphasizing its value.
