What is the foam on top of a Coke called?
Foam
Why would a Mento in a Diet Coke cause more fizzing than in a regular Coke?
The regular coke contains a higher amount of solute (sugar, corn syrup) compared to the diet version which uses concentrated artificial sweetener. The slightly-higher viscosity (thickness) of the regular Coke slows the nucleation of carbon dioxide on the surface of the Mentos candy. The thickness also means that it takes more force to lift the liquid out of the bottle (less height to the gas-driven foam fountain).
Will Ajax explode in diet coke?
Yes, mixing Ajax, a cleaning product, with Diet Coke can cause a dangerous chemical reaction. The carbonation in Diet Coke can create a significant amount of foam and pressure when combined with certain cleaning agents. This can lead to an explosive overflow, which is hazardous. It's important to never mix household cleaners with food or beverages.
Why do pop rocks make coke fizz?
it is due to the carbon dioxide reacting with the chemicals in the coke making it foam.
What chemical reaction happens when you put mentos in Diet Coke?
When Mentos are dropped into Diet Coke, a rapid physical reaction occurs rather than a chemical one. The surface of the Mentos candy is covered in tiny pits, which facilitate the rapid release of carbon dioxide gas dissolved in the soda. This causes an explosive eruption of foam as the gas escapes quickly, resulting in the iconic geyser effect. The reaction is enhanced by the absence of sugar in Diet Coke, which allows for a more vigorous release of gas compared to regular soda.
What is a creative title for Mentos and coke?
It is an ongoing unofficial competition to create the highest jet of foam generated by Diet Coke and Mentos. The current record is held by the Mythbusters.
What are Variables for coke and pop rocks experiment?
In the Coke and Pop Rocks experiment, the independent variable is the type of soda used (e.g., regular Coke, Diet Coke, etc.), while the dependent variable is the reaction observed, typically measured by the amount of carbonation or foam produced. Controlled variables include the amount of Pop Rocks used, the temperature of the soda, and the environment in which the experiment is conducted. These controls ensure that any differences in the reaction can be attributed to the type of soda rather than other factors.
Can Diet Coke explode with other mint?
Yes, Diet Coke can create a rapid release of gas and foam when combined with mint candies, such as Mentos. The rough surface of the mint provides nucleation sites for carbon dioxide bubbles to form quickly, leading to an explosive reaction. This phenomenon occurs regardless of whether the soda is regular or diet, due to the carbonation in the drink. Caution should be exercised if attempting this experiment, as the reaction can be quite vigorous.
How does alka seltzer react when mix with Diet Coke?
When Alka-Seltzer is mixed with Diet Coke, a rapid reaction occurs due to the effervescent properties of the Alka-Seltzer, which contains citric acid and sodium bicarbonate. This reaction produces carbon dioxide gas, leading to a vigorous fizzing and bubbling effect. The carbonation in Diet Coke enhances the reaction, causing a potential overflow of foam and bubbles if the mixture is not contained. This combination can create an explosive effect, so caution is advised when mixing them.
Why is Diet Coke and Mentos a double replacement reaction?
Diet Coke and Mentos create a vigorous physical reaction rather than a chemical double replacement reaction. When Mentos candies are added to Diet Coke, the rough surface of the Mentos disrupts the liquid's surface tension and allows carbon dioxide gas that is dissolved in the soda to rapidly escape, resulting in an explosive fountain of foam. This reaction is primarily a physical one involving nucleation, not a chemical reaction where bonds are broken and formed.
Why is Diet Coke and mentos a chemical change?
The surface of a Mentos is not smooth; it has microscopic pits, or nucleation sites, on it. These pits cause the CO2 in Diet Coke to come out of solution very quickly at the bottom of the bottle. The result is rapids release of the CO2 and foam in an explosion. This is actually the physical change that occurs. Due to the addition of caffeine, potassium benzoate, and aspartame with the CO2 in the Diet Coke, the reaction is much greater--this would be the chemical change.The Mythbusters did an entire show devoted to discovering why this happens. See the related link below.
Why does one kilogram of foam take up more space than one kilogram of rock?
rock is much more dense than foam. It's like a full bottle of coke weiging more than an empty bottle of coke.
