Spotlight on Carbonated Soft Drink
A soft drink is a beverage that does not contain alcohol. Carbonated soft drinks are commonly known as soda, soda pop, pop, or tonic (northeastern USA) in the United States, soda or pop in Canada, fizzy drinks in the United Kingdom and sometimes minerals in Ireland. The name "soft drink" specifies a lack of alcohol by way of contrast to the term "hard drink".
In the 1770s, scientists made important progress in replicating naturally carbonated mineral waters. Englishman Joseph Priestley impregnated distilled water with carbon dioxide. Another Englishman, John Mervin Nooth, improved Priestley's design and sold his apparatus for commercial use in pharmacies.
Carbonation occurs when carbon dioxide is dissolved in water or an aqueous solution. This process yields the "fizz" to carbonated water and sparkling mineral water Effervescence is the escape of gas from an aqueous solution. The term is used to describe the foaming or fizzing that results from a release of gas.
"Fizz" is a word used to describe the action or sound of gas bubbles moving through and escaping from a liquid. Fizz also describes the formation of a foam of this gas and liquid at the top of the liquid's container.
