What is carbonated drink
Carbonated drink is a drink added with carbon dioxide gas. Carbon dioxide itself is colorless and tasteless. In the environment of cooling and pressure, carbon dioxide is easy to dissolve into the water, forming carbonic acid. Each liter of water can dissolve 8 grams of carbon dioxide. Simply put, carbon dioxide + water = carbonic acid. It is this acid that causes the tingling of the tongue. Carbonated drinks are based on carbonated water, which often need to be seasoned with sucrose and spices. Generally, carbonated drinks contain more than 90% water.
Carbonated drinks can produce carbonation, and the reason why carbonated drinks produce bubbles and rattling is the reason that carbon dioxide gas escapes in beverages. Carbonic acid is very unstable. Under the condition of high temperature and low pressure, it will decompose rapidly and release carbon dioxide gas. Carbonic acid can be produced not only in nature, but also by artificial synthesis.
Carbonated drinks include not only the cola we drink in our daily life, but also soda water, beer and even spring water. But spring water is a kind of carbonated drink from nature. It absorbs carbon dioxide from the ground. The carbon dioxide contained in beer is also produced in the process of natural fermentation. Soda and cola are typical artificial carbonated drinks. These carbonated drinks are also considered as' soft drinks'. Soft drinks also refer to those non-alcoholic drinks - those containing alcohol are usually referred to as' hard drinks'. Therefore, lemonade is a soft drink but not necessarily a carbonated drink.
