Sulfate

compared the flame color with the colors in the chart. In order to identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify a chloride, equal amounts of the unknown solution, 6M HNO3, and AgNO3 are mixed together and if a white precipitate is formed, the test is positive. To identify a sulfate, equal amounts of the unknown, 6M HCl, and BaCl2 are mixed, and the presence of white precipitate yields positive results. To identify a…

To carry out the experiment we need to get caffeine into a solution. We used a solid-liquid extraction by adding 14 tea bags into a 1L beaker with 6g of sodium carbonate, 250 mL of tap water and bringing this to a boil for five minutes on a hot plate. Sodium carbonate is a weak bronsted base, that neutralizes tannic acids extracted from tea, that interfere with the later sublimation operation.(1) We turned the heat off after five minutes, added ice cubes to cool the mixture to room temperature…

the recycle bin, it would be hazardous and explode. This experiment was a success, it was easy to see that after heating the masses changed after the water molecules were released as vapor, therefore it was a lot easier to determine what copper sulfate, and magnesium chloride actually weight was.…

T. Heinze et. al. reported the synthesis of new 6-deoxy-6-pheylethylamino cellulose derivatives with DSamino 0.4-0.6 by nucleophilic displacement of cellulose tosylates (DSTos 0.74 and 1.29) with a racemic mixture of 1-phenylethylamine under homogeneous conditions, in DMF/H2O82, scheme 30. The optical properties of these deoxyamino cellulose derivatives was studied. A regioselective synthesis of 6-amino-6-deoxycellulose, 6-N-sulfonated, and 6-N-carboxymethylated deoxycellulose were…

GENTAMICIN The drug selected for study is Gentamicin. Gentamicin is an aminoglycoside antibiotic composed of a mixture of related Gentamicin components and fractions and is used to treat many types of bacterial infections, particularly those caused by Gram-negative organisms. Isolation and Preliminary studies 2 demonstrated that it is a mixture of basic, water soluble antibiotic containing the aminocyclitol 2-deoxystreptamine and two additional amino sugars. Chromatographic separation of…

A large majority of environmental scientists, professors, conservationists, engineers, and, in many cases, the average civilian, has realized the potential of disaster that can be caused by the rapidly-changing climate within the Earth’s atmosphere, expressing this in speeches and writings. Doing this, they are right, as one day we will witness the effects, which this paper will explain, caused by our own daily actions and the actions of other beings, including “Mother Nature”. Climate is…

a global cooling effect. Volcanoes are a natural mechanism through which aerosols are put into the atmosphere. One example of an aerosol, particularly a volcanic aerosol is sulfate (SO4). Volcanoes release sulfate when they erupt and create a global cooling effect, this cooling effect is particularly effective when the sulfate reaches the stratosphere which is about 10 km up. The mount Pinatubo eruption of 1991 had a global cooling effect, this effect was noted by a drop in the rate of warming…

Error Prevention in Nursing Nursing errors commonly are related to medication errors, documenting errors, infections, patient falls, and equipment injuries. According to the Institute for Safe Medication Practices (ISMP), around 42% of healthcare related life threatening events and 28% of medication adverse reactions are preventable (ISMP, 2013). Therefore, health professionals, especially nurses play a key role in reducing and preventing risky situations that threaten the health of patients. In…

Do you ever think about the mysteries of space? Have you ever wondered if there’s water somewhere besides Earth? Do you think there’s possibly more to the solar system than we know? Mars is the famous red planet we all know of, but it may be more than it seems. To understand the planet of Mars, one must know about its various geographical features, types of weather, and signs of water.The first key of knowledge that you should know about Mars is its many geographical features. Mars is home to…

of the reactivity series, and strong bonds break less easily. For example, copper is near the bottom of the reactivity series, and copper sulfate (CuSO4), begins to decompose at about 200 degrees Celsius, increasing rapidly at higher temperatures to about 560 degrees Celsius. In contrast potassium is near the top of the reactivity series, and potassium sulfate (K2SO4) does not decompose at its melting point of about 1069 °C, and does not decompose even at its boiling…
