would you do? Firstly I would use a standard sample of water to test all the different pathogens and qualities within it as a control group. Then I would test the contents of the new water made from the iodine bottle. I would test it with 2 variables of just shaking the bottle and leaving it at 20 degrees Celsius and also with the water warmed. The using each of the 2 types of water that can be formed from the iodine bottle I would proceed to test the water and compare it to the standard to see if all the bacteria Borne pathogens were destroyed after following the instructions of the iodine bottle. 3. The following is a procedure taken from the 1990 US Pharmacopeia for making a tincture of iodine: What is the purpose of alcohol (ethanol) in this procedure? Ethanol is used to make the iodine more soluble to water because the iodine and water are insoluble to one another. But ethanol and iodine are slightly soluble and ethanol and water are soluble.

Describe a New Inquiry: What if ethanol is not used in the iodine and water mixture? What would be the causes and effects on using this iodine tincture without the ethanol?

Min Heying Lab 1- Southside Seaweed Seaport Confidence Report In the beginning of the lab, both I and my lab partner came fully prepared with a summary and flow diagram of the procedure. We began the examination firstly by writing detailed observations of the physical appearance of all chemicals used within the lab. We cut dried seaweed into approximate ½ inch pieces. When using the scale, we made that it was read in grams and we reset it to zero. Once the scale was at zero, we weighed our samples of dried seaweed until we reached 6.02 grams. We then recorded the weight of the seaweed and the appearance of it into our notebooks. From there we placed the seaweed into a beaker and filled it about three quarters of the way with distilled water. We agitated the seaweed to remove any impurities that can be on the surface of the seaweed by stirring it with a glass rod. We made placed all used materials on a paper towel on our bench also to insure that no impurities from our work bench would be crossed over to the experiment. We then poured out the water, leaving only the seaweed remaining. We then measured 40 mL of distilled water from a graduated cylinder.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
