There are 7,000 Coca-Cola products consumed worldwide every single second. In soda, the phosphoric acid causes tooth enamel decay and the need for it to be carbonated. In fact, the levels of acid found in sodas are equivalent to the acids in batteries and there are many hazards for your teeth related with the high sugar amount in sodas. Drinking soda has been shown to contribute to tooth decay. Clearly, the sugar consumption involved in drinking soda is mentioned for causing tooth decay. However, the acid in soda has been shown to erode tooth enamel, leading to dental cavities as well. In fact, the acid in soda can begin damaging enamel just twenty minutes after drinking soda. Carbonated beverages get their fizz from the gas, carbon dioxide. When the bottle is capped, carbon dioxide dissolves within the soda from the pressure exerted on it. Formation of the bubbles increases pressure inside the bottle. Forced up the narrow neck, the fluid and bubbles burst from the high-pressure environment of the bottle to the lower pressure of the atmosphere. Soda is a very vigorous acid that needs partial pressures, gases, and solutions in order to keep the soda carbonated. Soda is an acidic solution that can be harmful and damaging to your body. PH measures how acidic or basic a solution is. Acids have a pH of less than 7 and bases have a pH of more than 7.The pH of sodas can be very acidic because they are low on the pH scale. Acids have a sour taste, are able to neutralize bases, and are able to donate a hydronium ion. Strong acids are able to form ions by dissociating completely. The pH of different sodas shows how acidic they are. For example, RC Cola has a pH of 2.4, cherry coke and coke have a pH of 2.5, Root Beer, which is the best soda for you, has a pH of 4.0 and battery acid has a socking pH of 1. Many diet and sugared sodas are nearly as damaging to dental enamel as battery acid. Drinking soda for a long period of time can lead to significant enamel lose,...
