The chemistry of the carbonation of soft drinks

  1. 1. By: Davis Duncan
  2. 2.  Have you ever noticed that if you shake up a Cokeit will fizz as you open it? How about how a “flat”soda doesn’t taste as good as a regular soda? This all has to do with the chemistry of thecarbonation of Soft Drinks. Placing high amounts of Carbon Dioxide into thebottle allows for this process to occur (Haase 2).
  3. 3.  Henry’s law (p=(kH)(c)) what goes into the fizzingand bottling of Soft Drinks (Rehmeyer 1). Carbon Dioxide reacting with water to formCarbonic Acid explains the chemistry behind thetaste of soft drinks (Stewart 1).
  4. 4.  Henry’s law explains why a soda willbecome flat slowly after it has been opened. By opening the can or bottle of soda, thepressure (p) decreases, Therefore Carbondioxide’s concentration (c) in the soda willalso decrease. Surface tension is the only reason that thesoda does not spray carbon dioxide in theface of whoever is unlucky enough to openit (Rehmeyer 1).
  5. 5.  The cans andbottles aredesigned to hold upto 20 atm ofpressure, and thesoda typicallycontains over 2atm, which willdecrease to 1 atmupon opening(Rohrig 11).
  6. 6.  Carbon dioxide reactswith water once it isplaced into the bottleforming carbonic acid(H2CO3) (Rohrig 11). Carbonic acid creates asmall pain that the braincounteracts by sendingout signals “that willimprove your mood”(Stewart 1). This explains why a sodawill taste worse after ithas “gone flat” (Clough1).
  7. 7.  Carbonic acidexplains theaddictions peopleobtain to theseunhealthy drinks,as seen by peoplethat will drinkcaffeine free anddiet soda (Stewart1). Henry’s Lawexplains whybottling company’sneed to make thebottles able towithstand severalatm of pressure(Rohrig 11). It alsoexplains why a sodagoes “flat”(Clough1).
