Is it true that the acid in soda/pop can cause some aluminum from their cans to disolve into them?

The soda cans he a thin film inside to protect the aluminum. However if the film is scratched it "may" have some long term effect. Years ago they used tin in the cans and experienced problems.

Carbonic acid formed by the CO2 in the soda.

No because digestive acid has a lower pH than coke.  Also, the coke would enter the bloodstream.

Embedded aluminum roof flashing, aluminum water stops, aluminum electrical conduit, introduced aluminum powder (sometimes used to foam concrete), or embedded structural aluminum shapes may all corrode in concrete or mortar. In all cases, a reaction that forms aluminum hydroxide and hydrogen gas occurs, and may cause expansion and cracking of the concrete or mortar. The common use of calcium chloride (or other alkali compounds), and dampness of the concrete increases the reaction rate. Usually, coating the aluminum with bituminous paint, impregnated paper or felt, plastic, or an alkali-resistant coating will prevent or sharply reduce the corrosion.

Yes, lemon juice and vinegar will cause iron to rust as well. It's like that old story where they say that putting a tooth in a can of coke for a day will cause the tooth to dissolve, yes it will, but the same could be said for putting a tooth in a glass of orange juice for a day as well. It's the acid in coke that causes the effects you're talking about, an Orange and Lemon juice and Vinegar all have more acid in them than coke does.

When in the bottle or can the solution is in equilibrium with the partial pressure of C02 equal to the pressure in the can. When the can is opened the pressure in the can drops (the ffffft or hiss sound you hear) and now the partial pressure of C02 in the soda solution is greater than the atmospheric pressure. This results in C02 coming out of solution, which causes bubbles to form. The bubbles represent a separate phase, which is a heterogeneous mixture rather than the homogeneous mixture prior to opening.\nNote that the CO2 levels does not completely equilibrate upon opening. Once the solution has come nearly to equilibrium (re CO2), the soda is said to have 'gone flat' and is no longer fizzy.\n\nI'm not sure the presence of oxygen has anything to do with this phenomenon.

FIRST OF ALL WHY THE SODIUM CHLORIDE IS HARM FULL TO HUMAN ??BUT THE ANSWER IS WRONG TEE Na Cl react with aluminum to produce hydrogen and sodium aluminum oxide. and a lot of heat. if the aluminum is in the powder form which will produce lot of heat and H2 which will cause a blast. do it your self proof the H2 with adding a balloon to the reacting bottle and let the balloon fly.

Depends on the manufacturer and the initiators they use. Usually, if its "acid free", it will say so on the box that you bought them in.

No.\n\nwww.mythbusters.com a TV series looked into a number of cola myths and found that modern pennies do not dissovle in cola,. In fact a dirty oild one will become new and shiny looking.

Yes. It's one of the main causes.\n\nhttp://zappa.ultrakohl.com/medstud/Meddocs/Panc2.htm

I've heard that it does....my sister always used to preach it so i thought i'd try it....and then i read it in a magazine somewhere....i think it's something to do with the acidity but i don't think it melts it all.....just lowers it..

Not knowing what mentos are, I can't give you a full answer.  However soda pop has a lot of dissolved CO2, which I imagine is forced out of solution.  So you'll have one or both of the two options\n\n1 the mentos act as a surface catalyst for the CO2 to adhere to and congregate into gas bubbles\n\n2 something in the mentos dissolves into the soda pop forcing the "precipitation" of CO2 Gas

yes, it causes.\n\nIf u take more sodium it will bring out chloride from stomache walls.\n\nSodium+Chloride= acid.\n\nso restrict your sodium daily to 10 gm

Because if the composition is too acidic or too basic one way or the other, the soda could be toxic.\n\nAlso, it wouldn't taste good or sell well.

I don't know if deodorant is bad for you, but I DO know that is it good for everyone else around you....lol.\n\nActually, I wouldn't really worry about the aluminum too much. If you think about it, a lot of the pots we cook in are made out of aluminum, we wrap our leftover food in aluminum foil, and almost all of our canned foods come in aluminum cans. I wouldn't be too concerned if I were you.\n\nSome people say that the aluminum in deodorant causes cancer or alzheimer's, but that is not true.

Pepsi is carbonated (contains bubbles of carbon dioxide).  This means that there is actually less volume of frozen liquid to be melted.

think high concentrations of ions can denaturate proteins, an d some ions in particular...
