The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the vinegar for two days I removed one from the vinegar, washed the eggs and placed it in the corn syrup. Corn syrup…

was to test and examine how different contaminants affect ground water. The experiment had interesting results whereby when I filtered vinegar through a media containing dirt resulting material as clean. I report that it surprised me since I did not expect that any of the contaminants used in the experiment would affect water equally the same way it affected vinegar. I had to think critically that the water probably have dirt that has been mixed with the ones that was filtered. From the…

I noticed that the pH is more acidic when vinegar was added to all of the vegetables. A pH less than 7 in considered a acid, 7 is neutral, and over 7 is considered an base. If you refer back to the tables, the pH was the lowest when vinegar was added to these vegetables, numbers including a range from three to five. When the saucepan was covered and cooked in water for 15 minutes, it tended to cause the vegetables to be one of the mushier ones out of the other cooking treatments. Numbers…

Data Analysis An evident observation from Graph 1 was that the ampicillin has the largest average diameter of the zone of inhibition at 26.50 mm, followed by apple cider vinegar, oil of oregano and then Manuka honey. The blackstrap molasses, colloidal silver, control and onion extract did not cause a zone of inhibition. Blackstrap molasses seemed to have spread throughout all its trials, however, it did not inhibit the growth of E. coli JM101. In actuality, Photo 2 shows that the bacteria…

used in week 2. Discussion (Week 2): During Week 2, we sought out to determine if our household remedies of Lemon Juice and Apple Cider Vinegar could successfully dissolve our calcium phosphate and calcium oxalate kidney stones. We also attempted to find the Ksp of our solutions and compare them to data found on the Internet. Since the apple cider vinegar did not give us any results for the experiment, we had to rely solely on the lemon juice. Despite our best efforts, we could not find…

Fausto B. Mariano L. Daniel E. Diego R. Ms. Gudiño Science 3B 27/OCT/15 Lab Report Osmosis -Research Question: How will uncovering the egg shell by exposing the egg to vinegar will make it possible to understand the osmosis process in action? -Background information Diffusion: It's the net movement of molecules down a concentration gradient. This process allows small molecules like water and carbon dioxide to cross the Plasma Membrane. (Movement of dense areas to less dense areas.)…

The way that the egg was prepared in advance was because the teacher soaked the eggs in vinegar for about two days. The reason why the teacher soaked the eggs in nothing but vinegar for 2 days was because, when the eggs soaked in vinegar for 2 days, it made them like water balloons. Soaking the eggs in vinegar for 2 days is very important in this lab. The reason why it is very important to soak the eggs in vinegar for 2 days is so that it removes the shell from the egg and you can rub the…
