Diet Coke And Mentos Physical Or Chemical Change
Cut a piece of paper so that it is as wide as a roll of mentos.
Diet coke and mentos physical or chemical change. It has microscopic pits or nucleation sites on it. Diet coke has a massive amount of dissolved carbon dioxide in the liquid. You might think that there is some ingredient in a mentos candy that causes a chemical reaction with the soda pop like the way baking soda reacts with vinegar.
Close off one end of the tube by cutting a little circle or square of paper and taping it to one end of the tube. Use masking tape to tape the tube closed. The reaction is largely physical not chemical.
Many students have come to believe that it is a chemical reaction between the mentos carbonates and the diet coke acids that makes the fountain work however it turns out that research findings have turned up a quite different explanation. Because no new chemical compounds are formed the escape of co 2 from a soda is known as a physical change. Wrap the paper around the pack of mentos to make a tube.
The mentos and coke are unchanged just as the co2 is unchanged in this physicalreaction the reaction of diet coke and mentos is a physical reaction. The mentos and coke are unchanged just as the co2 is unchanged in this physicalreaction the reaction of diet coke and mentos is a physical reaction. Without splitting hairs regarding what happens to carbon dioxide co2 when it dissolves in water we.
The surface of a mentos is not smooth. These pits cause the co2 in diet coke to come out of solution very quickly at the bottom of the bottle. Links can be found below to learn more.
The basic science of the coke and mentos reaction is fairly straightforward. Carbonated drinks get their fizz from dissolved carbon dioxide which is pumped into the bottles at high pressure to make it dissolve. Links can be found below to learn more.
