IntroductionDiet Coke is a popular, calorie free soft drink. It is a modified version of the original Coca Cola. It first appeared on store shelves in 1982. There are many different variations of Diet coke such as, caffeine free, lemon, lime, raspberry, black cherry vanilla, sweetened with Splenda, and Diet Coke plus. In other countries there are different variants of Diet Coke too. Diet Coke may taste different in different countries. I chose to research the chemistry of Diet Coke because it is my favorite type of soda. I am curious about how it is made, and what the ingredients are that it is really made with. My life is affected by diet coke because I drink it at least once a week. Many Americans drink multiple cans of Diet Coke each day too. The average American consumes about forty gallons of soda each year. Since 1978, soda consumption in the us has tripled for boys and doubled for girls.

Chemistry's Role
Carbonated water is usually artificially produced by pressuring carbon dioxide into water at the bottling plant. If one wants to make carbonated water at home, they can buy seltzer bottles as well as soda chargers. Carbonated water is man made, not naturally occurring. Chemistry processes are used to make carbonated water.
Caramel Color is made by a carefully controlled heat treatment of carbohydrates, generally in the presence of acids, alkalis, or salts, in a process called caramelization. It is more fully oxidized than caramel candy. It is man made, not naturally occurring. Chemistry processes are used to make caramel color.
