Vocabulary you need to know: • Acid=a substance with a sour taste. • Base= the bottom support of anything; that on __which__ a thing stands or rests: a metal base for the table.• Molecule= any very small particle.• pH= __phenyl.__
• Chemical reaction= A process in which atomsof the same or different elementsrearrange themselves to form a new substance. While they do so, they either absorb heat or give it off.

• Reactant (in a chemical reaction)= a person or thing that __reacts__.
• Product (in a chemical reaction)= a thing produced by labor: products of farm and factory; the product of his thought.
• Phosphoric acid (and its chemical formula)= any of three acids, __orthophosphoric acid__, H 3 PO 4 , metaphosphoric acid, HPO 3 , or pyrophosphoric acid, H 4 P 2 O 7 , derived from phosphorus pentoxide, P 2 O 5 , and various amounts of water. Also we found out was that the nails did not actually disolve they just rusted ans the coke took the shine away

... The independent variable in this experiment would be the size of the nails. The dependent variable would be if the nails will actually desolze a nail. The constant variable will be the amount of coke would be in the beakers.
step 1) take three nails (weigh them and mesure them before any of this and write it down in your notebook) of the same size that are the same metals.
step 2) put 100ml into the beaker full of coke.
step 3) drop one nail into one of the beakers filled with coke (repeat this step with the other beakers and nails)
step 4) wait for three days and take the nails out.
step 5) weigh the nails and mesure the nails to see if they have changed at all.
step 6) see if there is any difference in the nails.
step 7) write down all of the differences in your notebook.

Coclusion
Claim- We found that if you leave a nail in coke for 3 days then they will lose 0.4 grams and if you leave a nail in acid for 3 days then the average nail will llose 0.34 grams. So in 3 days the nails will not fully dissolve, but, they will dissolve a little bit if you leave the nails in coke or acid for 3 days. The myth is plausable.

Evidence- The coke did not dissolve the nails in 3 days and neither did the acid. We put three nails in a beaker full of coke for three days and put nails in a beaker full of acid for three days and neither one dissolved a full nail.

Explanation- I think the coke and acid didnt dissolve the nails in three days because the acid in the coke (citric acid and phosphoric acid) and the acid in the acid bottles were not strong enough to dissolve a full nail in three days but if we would leave it in the beakers for about a month then i think it would fully dissolve the nails.

Summary- We put 3 nails in 3 different beakers of coke and another 3 nails in 3 different beakers of acid. We are trying to see if 100ml of coke can dissolve a nail in three days and if a 100ml beaker of acid can dissolve a nail in three days. We left the nails in the coke and acid for 3 days. The beakers were each 100 millaleters full and each had 1 nail in it that weighed 4.5 grams. After we left the nails in the coke and acid for three days each, the nails didn't fully dissolve but they did dissolve a little bit. The average acid nail after three days lost 0.34 grams of weight. the coke nails each lost 0.4 grams of weight. So if you leave a nail in either coke or acid for a longer period of time it could have a chance of fully dissolving a nail. So this myth is plausable ( it could happen but we aren't sure).

We need to look up our vocab. words
Soda is carbonated, meaning that it has carbon dioxide dissolved in it. Some of this carbon dioxide (CO2) reacts with water (H2O) to form carbonic acid (H2CO3), which makes it acidic
Large Scale Procedure

Question: Can The Acids In Coke Really Dissolve A Nail??
Independent Variable: The Size Of Nails.
Dependent Variable: The Amount Coke.
Constant Variable: The Amount Of Coke And The Type Of Metal.
Hypothesis: I Don’t Think The Acids In Coke Will Be Strong Enough To Dissolve The Nails.
Materials:

  1. A 2- Liter Bottle Of Classic Coca-Cola.
  2. Three 200ML Beakers.
  3. 3 Of 2 Different Types Of Nail.
  4. A Ruler.
  5. A Scale.

Steps:
  1. You get three nails (All Nails Have To Be The Same Size).
  2. First, grab your 3 200ml beakers and put them on a table.
  3. Next, you open your 2-Liter Bottle Of Coke.
  4. Then You Weigh Each Of Your Nails.
  5. Then Pour 100ml Of Coke Into Each Of The Beakers.
  6. Drop one nail into each of the beakers.
  7. Wait for 7 days and check it.



Ethan
Step one / bring matierials , wheigh nails./2 / dump 100 ml of coke into 3 beakers. /3 / put 3 three nails into the beakers 1 nail in each. /4/ Wait 4 days then see if the nail was disolved by the coke./5/ Write down in your notebook what happend if it worked and why you thinked it worked, if it didnt you need to no why it didnt work. weigh the nails and see if it disoved it a little bit.

Let's see, I have to agree with the person that said that stomach acid is more dangerous. Did you know you get more phosphorus out of cheese? In addition the whole dissolve a tooth in 10 days issue.. My question is who in the world is soaking their teeth in phosphoric acid for ten days? Even still, since cola products are liquid, they pass through the urnine system within a couple hours to a day. Sorry but I don't find those tests valid when it comes to human phsiology.
Also, the FDA has approved it, and it has been proven that the human body does need certain amounts of phosphorus and aids in bone strength.
That's my thought's for phosphoric acid. And if you're really concerned about it, Pepsi has more phosphoric acid in it than Coca-Cola. The percentage value for Coke is .000341% and Pepsi is .0003926% (I did the titration experiment myself.
Our large scale test didnt work coca cola can't dissolve a nail in 3 days. The acids in the coke isnt strong enough to dissolve a nail in 3 days. but our nails did lose .3 of a gram in three days. Lets say that the nails lost .5 grams every 3 days that means it would take 18 days for a nail to dissolve approxamently.

Small Scale Test Conclusion
Claim- we found out that coca-cola can not dissolve a nail, it only took the shinnyness away. otherwise it stayed the exact same as before we put it in the coke for three days.

Evidence- our evidence is that we kept the nails from after the test and got the exact type of nails and compared them together. also we are making a video of the experiment and another piece of evidence we have is the test results from our notebook.

Explanation- i think it didnt desolve the nail because the acids in the coca-cola wasnt stronge enough to desolve a piece of metal.

Large Scale Test
Can the acids in coke really dissolve a nail?

variables

independant- size of nails

dependant-the amount of coke

constant- the mount of coke and the type of metal for the nails.

hypothesis- i think the coke/acids will not be able to dissolve the nail because the acids arent strong enough to dissolve a metal nail.
materials for experiment- you need 3 nails (all the same size), a bottle of coca-cola, 3 200ml beakers, a journal, pencil, an something to weigh the nails with.

The independent variable in this experiment would be the size of the nails. The dependent variable would be if the nails will actually desolze a nail. The constant variable will be the amount of coke would be in the beakers.
step 1) take three nails (weigh them and mesure them before any of this and write it down in your notebook) of the same size that are the same metals.
step 2) put 100ml into the beaker full of coke.
step 3) drop one nail into one of the beakers filled with coke (repeat this step with the other beakers and nails)
step 4) wait for three days and take the nails out.
step 5) weigh the nails and mesure the nails to see if they have changed at all.
step 6) see if there is any difference in the nails.
step 7) write down all of the differences in your notebook.
Procedure- step 1, you get 3 nails (all three have to be the same size) and three beakers full of coca-cola (fill all the beakers with the same ammount of coke). also weigh and mesure the nails before yo start the experiment.
Step 2- fill the beakers with the coke and put one nail into each beaker and set them on a table or a solid type of surface.
Step 3- let the beakers with the nails and coca-cola in them set for three days.
Step 4- take the nails out of the beakers once they have set in the coke for 3 days.
Step 5- compare the nails you tested with to the exact type of nails that havent been tested on.
Step 6- see if there is any difference in weight or size between the tested nails and the new nails.
Step 7- write your results on a piece of paper and make sure you write how much the nails weighed and how big they were before the experiment and how they are after the experiment.
