Sodium hypochlorite

In this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…

With the acid, HCl, the pH of the tap water went from 7 to 1.5 after 30 drops, indicating that the concentration of hydrogen ions increased significantly. With the base, NaOH, the pH of the tap water changed from 7 to 12 after 30 drops, indicating that the concentration of of hydrogen ions decreased significantly. These changes occurred in the tap water because there are no chemical buffers present in water. In the potato homogenate, when 30 drops of HCl were added the pH changed from 6 to 3.5…

Discussion and Scientific Explanations The main goals of this experiment was to find the unknown compound, to discover the compounds chemical and physical properties and create two synthesis of the compound and compare the two compounds. We found out our compound was ionic because the compound dissolved in water, but not in toluene or acetone by using a solubility test, results on Table 1 of the group lab report. On page 59 of the Cooperative Chemistry Laboratory Manual is a chart on suggested…

The biology 151 lab groups at the University of North Dakota conducted an experiment to find out the effects of sodium chloride on the plants that are not naturally grown in salty soils. Wisconsin Fast Plants, which are naturally grown in low to no sodium chloride concentrated soils, were planted and grown in several different salt concentrations to discover whether the plants grew better or worse in given soil concentrations. After multiple measurements, the results came back that the plants do…

Out of many early photographic processes, I select the Anna Atkins Photographs of British Algae: Cyanotype Impressions, 1843 Cyanotype. I select this process because the color of this picture is very different to the others in the lecture making this photography stand out and get my attention. While I was doing my researches, I found out that the process to make this picture is not complicated, does not require a lot of materials, and needs a negative image which reminds me of the class activity…

Before beginning he experiment the physical appearance of all the chemicals being used needs to be written down. To begin the experiment 3 test tubes must be acquired; a boiling tube, large test tube and a small test tube. The large test tube must be completely dried with a paper towel and labeled R for Reactants. After that is done a piece of weighing paper should be placed on a balance and tared. After make sure the balance is correctly tared, a spatula must be used to collect 2 grams of…

Jessica Hill CHM 144M Section C Dr. Zhu Charles Dotse Aileen Decker 8 October 2015 The Quantitative Determination of an Acid in Carbonated Beverages Abstract: The basis of this lab was to juxtapose two different titration methods in their ability to identify the end point, calculate the molarity of citric acid in the two sodas, and apprehend the differences between polyprotic and monoprotic acids. In order to accomplish this, a traditional titration, with phenolphthalein, and a modern…

Experiment 15.2 Purpose: To show temperature effects on reactions and Le Chatelier’s principle. Materials: 2 test tubes, 2 eyedroppers, 2 beakers, 2 small cups, Clear ammonia solution, White Vinegar, Flame or stove, Pot, Water, Ice, a few leaves of red cabbage, and safety goggles. Question: How does equilibrium work with respect to temperature and concentration? Hypothesis: Depending on whether the reaction is endo-thermic or exothermic the equilibrium will shift to one side, this is also true…

Josie Nadaud CHM 144L-A Professor Jessa/TA Jess October 8, 2015 Experiment 5 Partial Formal Report Methods 1. Traditional titration with indicator dye (week one) First the 50mL buret was cleaned by filling it with distilled water and letting it empty three separate times. It was further cleaned by coating the inside with 5 to 10 mL of the 0.0468M NaOH titrant solution and emptying that into the waste beaker as well for three repetitions. 40.0 mL of 7-Up soda was diluted with 60.0 mL of…

1 There was no smell 2 When I pour the oil in the water I noticed the oil started to bubble to the top. So I got to stir the oil that’s when there were smaller bubbles. As I smell the water there was no smell to the water. 3 Pouring the vinegar in the water there was one change that I notice the water was darker after I added the vinegar. There was no smell even though I added to the water. 4 When I added the detergent to the water it started to look cloudy and there was bubbles. 5 I notice the…
