Does Diet Coke Float In Water
If you prefer video explanations.
Does diet coke float in water. The artificial sweetener used in diet coke is hundreds of times sweeter per unit volume than regular sugar. If you put a can of diet coke in a swimming pool it would not sink and still float. Cans of diet soda are usually less dense than water so they float.
In soda water the bubbles attach to the peanuts and the overall density of this combination is less than water so they float. The artificial sweetener used in diet coke is hundreds of times sweeter per unit volume than regular sugar. Why do peanuts float in a regular coke and sink in a diet coke.
The can of coke immediately sinks while the can of diet coke floats. Diet coke contains very small amounts of sweetener which does not contribute siginificantly to the density of the solution so it is essentially the same as the water it is floating in and hence it does not sink. Coke has about 11 teaspoons of sugar in each can which are taken up by water in the diet coke can.
Since sugar is more dense than water it is not surprising that the diet coke will be less dense than coke. The density of raisins and peanuts is greater than water so they sink. The can of diet coke contains less than one gram of sweetener resulting in a density nearly equivalent to that of water indeed slightly less so it floats.
Some instructors have adapted this demonstration as an experiment to teach students the principles of density and buoyancy. Many science teachers perform a demonstration in which they immerse sealed cans of coke and diet coke in a tank of water. Non diet soft drinks contain a lot of sugar about 40 grams or 8 teaspoonsful which makes a denser solution than water hence the can sinks.
Coke has about 11 teaspoons of sugar in each can. Because the high sugar content in regular coke makes it more dense.
