Our whole entire lives we come in contact with various liquids. Each liquid has their own pH level. There is a pH scale which measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral and a pH less than 7 is acidic. A pH greater than 7 is basic. The higher the acidic level the more harmful it is to other objects. In this experiment Coca Cola, stomach acid, water, and sprite will be tested to see which substance dissolves a protein fastest and which substance can detoxify a nail fastest. My hypothesis is that Coca Cola, with a pH of 2.8, will beat the other liquids in both tests. ======

Coca Cola is a carbonated drink and is said to be able to remove blood from the road, clean a dirty penny, and more. The pH level of Coca Cola is 2.8, which is very acidic. Stomach acid breaks down almost everything you eat. It has a pH level ranging from 1.5 to 7.0. The pH level varies depending on what you eat. Water has a pH level of 7, which is non acidic. Water is the control in the entire experiment. Lastly sprite is another carbonated drink. Sprite has a pH level of 4.08. ======

In this experiment I will need to take advantage of the lab equipment given to me. I will need to use 100mL beakers, spinner, goggles, stopwatch and a pair of tongs. The materials that I am going to be using to test my experiment are cubed cooked chicken, rusted nails, Coca Cola, Sprite, water, and diluted hydrochloric acid. I am going to measure out 50mL of each liquid and place them in separate 100mL. Test number one is to see which liquid can dissolve a protein, or cubed cooked chicken, the fastest. The beakers will be separately placed onto the spinner. The spinner will spin the liquid to speed up this procedure due to the time given. Once on the spinner the protein will be dropped into the liquid by the tongs, to prevent any dangers. This test will be done at least ten times. After every trial the time is going to be recorded in a table and the beaker cleaned out. The second test is to see which liquid can detoxify a rusted nail the shortest amount of time. Again, the beakers will be placed one by one onto the spinner and then the rusted nail will be placed into the liquid by use of the tongs. This test will also be done at least ten times as well and the times will be recorded into a table. ======

To make this experiment work I am going to need to the testing in school, with a teacher licensed to handle chemicals. Hydrochloric acid can be extremely harmful and all safety equipment would be in the science rooms if anything went wrong. Also, our lab tables in school have all the equipment needed to carry out this experiment other than the spinner, which I am going to get from Mrs. Fogell. ======

I think I have collected enough information to gather good results to prove my hypothesis correct or incorrect. I will need to carry out my experiment carefully and properly to get the best results possible. Out of Sprite, Coca Cola, water, and diluted hydrochloric acid, I think Coca Cola is the strongest. ======

 * 1) 2. Put the beaker on the stirring device. Place the magnetic mixer in the beaker and add a 1 cm3 chunk of the chopped chicken. **NO more using the magnetic mixer, just let it sit. Also, mash the chopped chicken until it looks chewed with the and pallet.**======

**#20. Repeat steps 15-17 for 50 mL of Water.**
NOT DOING THESE STEPS BECAUSE THE NAILS WOULD NOT RUST IN TIME!
 * 21. Repeat steps 15-17 for 50mL of Stomach Acid
 * 1) 22. Repeat steps 15-20 nine more times.**

10-29-09 Cut up chicken and did first trial with chicken and Coca Cola. Mrs.Fogell helped supervise. Started the electric mixer at speed 7 at 3:05pm but 4min into the testing we cranked it up to speed 9. We did this to see if the process would speed up or not.Stopped at 10min. The cube of chicken got darker around the edges and some small particles came off but that is prob due to the mixing pellet. 11-9-09 Set up 7 50mL of coke and 7 50mL of sprite in Mrs.Fogell's room. At 8:47am there is foam on the top of the coke trails but nothing on the sprite. There are bubble marks outside the glass on the lab table counter from the carbination of the drinks. No definite changes yet. 9:35am. Parts of the chicken in the sprite trails are starting to stick off. They look like spikes on a ball, otherwise no changes. In the coke trails, some of the foam has gone away and the chicken is starting to brown. Still no definite changes. 10:34am. Less bubbles are present in both the sprite and the coke. No changes at all in the sprite. In the coke more foam has dissapeared. The chicken has gotten browner. No definite changes yet either. 12:17pm. Less foam is on the coke trails. Chicken got a little browner. No changes at all in the sprite trails. Still no definite changes. May want to stir to try to simulate chemical reactions like inside the stomach?? but not sure. I am going to let them sit over night and check them in the morning for more time. 1:09pm. Barley any bubbles left in the coke trails. Still bubbles present in the sprite trails. Nothing has changed in either sprite nor coke. 1:50pm. The bubbles decreased in the sprite trails. There is little to no foam left on the coke trails. The chicken seems to still be browning because it got darker. Otherwise no changes have occured. 11-10-09 7:28am. There are no more bubbles present in either of trails. In the sprite trail there are fragments of chicken throughout the bottom and some at the top of the beaker. Show some sign of dissolving. Inn the coke trails there are also fragments of chicken at the bottom and some at the top of the beaker. The chicken looks to be completly browned. Show signs of dissolving. 1:22pm. Chicken seems to become whiter in the sprite trails. No more changes since last checking. Seems to be a film on top of some coke trails but again, no changes since the last check. 7:17am. Parts of the chicken have floated to the top and looks like a moldy uky ew. No changes in the sprite trails. Dec.9 7:29am. Started testing all over again. The only change this time is that i mashes the chicken cube until it looked chewed and then added it into the beaker of soda. So far both the sprite and coke's chicken are floating. No major changes. Dec.10 7:25am. in the coca cola trails there is disscolorationg but thats about it. In the sprite trails the chicken has become more pail. NO other major changes. Dec.11 7:14am The coca cola chicken was darker and some foam residue has started to gather. In the sprite trails nothing has changed. Some faint residue has started to come to the top. There are NO major changes. Jan. 5 I started the stomach acid trails. In 7 beakers there are mashed up chicken cubes. In the other 7 beakers they just remained cubes. I will check these tomorrow morning. Jan. 6 The mashed up chicken in the stomach acid has gotten whiter and broke apart more. The cubed chicken in the stomach acid has gotten slightly paler but no fragments came off.
 * stopping and changing procedure
 * Mrs.Fogell and i decided to start all over but this time we would mash the chicken cube instead of keeping it whole for more surface area and maybe get more results.**
 * only problem is that the nails are not rusting????**

Stomach Acid (mashed) six showed signs of decompostion taking place, one did not. Stomach Acid (cubed) all 7 seven showed no sign of decomposition Coke (cubed) 2 showed sign of decompostinon, 5 did not. Coke (mashed) 4 showed sign of decompostion, 3 did not. Sprite (cubed) one showed sign of decompostition, six did not. Sprite (mashed) three showed sign of decompostion, 4 did not.

Mrs.Fogell and i came up with the assumption that the soda trials needed the stomach acid and other components in the body plus the motion from the stomach while digesting to show full decomopstion. The coke started to brown, which showed the beginning but it was lacking some of its main components to complete it's task.

I came up with the assumption that the stomach acid trails needed the motion of the stomach while digesting and the other components added to complete the digestion trails. But the stomach acid, while mashed, showed the most progress in the digestion process.
