I think it is because the coke goes flat once it is opened and left out for awhile the acid is not as strong The reason the eggshell does not dissolve in the Coke is that the acid in Coke is phosphoric acid and calcium phosphate has a very low solubility. Calcium acetate is highly soluble so vinegar will easily dissolve the eggshell. Note that the phosphoric acid in the coke will do a pretty good job of cleaning lightly rusted cast iron or steel.
No. Since vinegar has more acid than coke and since coke has more acid than sprite, vinegar has more acid.
Coke and vinegar are both acidic, and so would make your acid reflux worse.
No Coke is not more acetic than vinegar because of the acid they contain. Vinegar has an acid called acetic acid that is a lot more powerful than the acid Coke contains which only effects the enamel on your teeth. So there you have it! Really you! ;)
coke works way better than pepsi
the acid level of lemon juice is less then that of coke or lemon juice. Its pH level is 3, while coke is 2.5 and lemon juice is 2.
They don't die from acid rain, it's less acidic than vinegar or Coke
Lemon Juice, vinegar, Coke, Tea and Coffee are Acid Milk is half neutral half acid. Tap Water is neutral.
Coke is an acid.
Mixing vinegar and baking soda will give you a bubbly acid. Coke and mentos will also make a nice display.
The acid in the cola will dissolve the egg shell (calcium carbonate) over time and you will be left with an intact membranous egg floating in some nasty soda. A similar effect can be seen by leaving an egg in vinegar.
Vinegar (Ethanol Acid), Fizzy drinks [soda, pop, coke, soft drink] (Carbonic Acid), Tea (Tannic Acid), Vitamin C products (Ascorbic Acid) and Lemons (Citric Acid)
Coke in and of itself is not an acid but a mixture of a variety of substance, some of which are acids. Coke contains carbonic acid and some phosphoric acid.
Me and my friends at school tried it as well it actually makes the egg shell thicker and harder to take the shell off and it becomes mouldy.
Yes, Coke has carbonic acid, which makes the fizz.
coke contain gastric acid
coke has the most acid
vinigar coke is sticky
coke has mokre carbonic acid
Depends, shell or no shell? Then i answer.
What is the acid that makes Coke and Pepsi fizz?
is phosphorous and phosphoric acid the same in coke?
