Please Note: This lab involves a lot of waiting for the gas collection. Make sure you allot yourself the full three hours to perform the experiments.
Observations: Use this table to record all your observations for each section of the experiment. Please use complete sentences.
Section in procedure|Observations|
1: Hydrogen|Bubbles were present, gas being produced gas appeared to be clear. Did appear ignite.|
2 : Oxygen|Bubbles were present, showing signs that gas is being produced gas is clear. Did appear to ignite.|
3: Hydrogen/oxygen mixture|Did not appear to be flammable. Match did not ignite |
4: Carbon Dioxide: Part 1|The lime water appeared milky in color when the gas was released into the solution.|
4: Carbon dioxide Part 2|The Bromothymol blue turned yellow in color when the gas was released into the solution|
4: Carbon dioxide Part 3|The lime water appeared milky in color when the gas was released into the solution.|
4: Carbon dioxide Part 4|As bubbles from the straw enter the clear limewater, it turns milky. After standing, the solution looks clear|

Summary of data:

Summarize your data in the following two tables. It is not necessary to use complete sentences here. If you did not test a particular property, please indicate so by using N/A.

Differential Staining

...MLT1 Experiment 5/Task 6 Differential Staining There are many different ways to stain bacteria for viewing under a microscope. For the most part these are categorized as “either simple, nonspecific or differential (specific) (LabPaq, p.128). The most common staining method used is Gram staining. Gram staining is a differential or specific method of staining. Gram staining is a way to tell the difference between gram positive and gram negative bacteria. The cell wall of the gram positive bacteria is made up of several “layers of peptidoglygan,” and “techoic acids,” (LabPaq, p. 128). This peptidoglycan is what absorbs the color part of the crystal violet stain causing the gram positive bacterial cell to appear violet colored when viewed with a microscope. In contrast, the cell wall of the gram negative bacterial cell is not as thick as that of the gram positive cell wall. Peptidoglygans are on the inside of the cell rather than in outer layers. The outer part of the gram negative cell is made up of phospholipids and lipipoly-saccharides (Betsy and Keough, 2005). The outer cell wall does not hold onto the violet color of the crystal violet and appears pink in color when viewed under a microscope. The purpose of iodine staining is to aid the bacteria to keep the stain by creating an iodine-crystal violet mixture that will not dissolve. Iodine is also known as a mordant in this case. A mordant is usually an inorganic oxide that when mixed with...

Mlt1 Task 2

...MLT1 TASK 2 Western Governor’s University April 02, 2015 Task: A. The difference between Facultative and Obligate aerobes is that while both aerobes require oxygen to survive facultative aerobes can survive with or without oxygen to survive. Obligate aerobes require oxygen to live and grow organisms, with facultative aerobes can grow live and grow organisms with or without oxygen depending on the certain conditions and organisms. B. According to labpaq (labpaq, received 2015) it stated it was very important to keep the temp at 37 degrees. 37 degrees is a prime temperature for S. epidermis and L. acidophilus bacteria that commonly live on the skin to grow. C. It is very important to control the growth of microbes one way to do this is with adequate aseptic technique. For example cleaning IV poles, blood pressure machines, stethoscopes using “sani wipes” or other disinfectants is appropriate. For proper aseptic technique in control growth on humans, I would use first and foremost proper hand washing, then things like iodine, alcohol, and hibicleanse. D. There are several forms of culture media. “Media can be either liquid (nutrient broth) or solid (agar).” (ScienceProf) “Very few forms of Microorganisms can degrade agar, so it usually remains in a solid form.” (Microbiology, Demystified, 2005) Agar slant puts the test tubes on its side to grow. Agar dishes are plates that lie flat to grow bacteria. “A culture made by inserting an inoculating nee...

Discussion and Review: Many bacteria are capable of motility, the ability to move under their own power. Most motile bacteria propel themselves by special organelles termed flagella. The bacterial flagellum is a noncontractile, semi-rigid, helical tube composed of protein and anchors to the bacterial cytoplasmic membrane and cell well by means of disk-like structures. The rotation of the inner disk causes the flagellum to act much like a propeller. Bacterial motility constitutes unicellular behavior. In other words, motile bacteria are capable of a behavior called taxis. Taxis is a motile response to an environmental stimulus and functions to keep bacteria in an optimum environment. The arrangement of the flagella about the LabPaq: MBK Page 112 Hands-On Labs, Inc. bacterium is......

Acid Base Chemistry

...discarded in the trash container. Exercise 3: Testing the pH of Household Products 5 household products were collected to be used for pH classification. The name of each chosen household substance was recorded in Data Table 3. It was then predicted for each substance whether it was acidic, basic, or neutral. A small amount of one substance was poured into a disposable cup. One cut piece of pH paper was used to determine the approximate pH of the substance and the value was used to categorize the substance as an acid, base, or neutral solution. It was also recorded in Data Table 3 whether the prediction was correct or not. The steps were then repeated for the remaining 4 household substances. All items were then cleaned and returned to the LabPaq kit for future use. Data and Observations: Exercise 1: Using the pH Paper and the Indicator BTB Data Table 1. Data Collected from Exercise 1.
