Sodium Nitrate

Strontium nitrate, the limiting reagent, was poured into the copper(II) sulphate solution, the excess reagent, rather than the other way around. This is a minor systemic error, because even if some of the strontium nitrate remained in its initial beaker, the beaker was thoroughly rinsed out multiple times. The error causes the final mass of the filter paper and precipitate to be slightly decreased, as not all of strontium nitrate reacts with the copper(II) sulfate. This can explain why the percent yield in 92.2%.

Although many researchers believe that our planet’s environment and ecosystems are facing many challenges due to livestock production, proponents of livestock production believe that the reason why the our environmental condition has worsened is not that we eat more meat — but because we eat less of it. Niman argues that instead of decreasing production, we should focus on producing meat that is more environmentally sound. She also argues that “Feed production—with all its attendant problems of fossil fuel consumption, soil erosion, greenhouse gases, and chemical pollution—can be avoided altogether” (Niman, 79). In “Defending Beef”, she explicitly criticises the FAO’s “Livestock’s Long Shadow” and questions certain statements

The pigment that we chose to create is a combination of the reactants copper nitrate and sodium phosphate. This combination will create a bright blue color. The balanced equation for this combination is 3 Cu(NO3)2 + 2 Na(PO4) = Cu3(PO4)2 + 6 Na(NO3).

7. Now heat the sample a second time for an additional 6 minutes using a high temperature flame. Then, once again, allow it to cool to room temperature. Weigh the cooled crucible, lid and sample after this second heating

Do you really know what is in your meat? What about what happens to the meat after it is slaughtered? Fortunately, the conditions have gotten much better throughout the years. But many years ago, in the early 1900s meat consumers bought spoiled and rat infested hams that were produced by the meat industries. Nowadays, the meat industry has improved to a certain extent. Today, about 80% of all U.S. feedlots are injected with hormones (Lerner). Americans should know what they are eating. This is important in the meat industry because they are the producers of all the meat that we eat. The meat industry has improved and is much better than the 1900s, but still not at as ideal as everyone thinks it really is.

If you wish to avoid nitrates in your body, it is recommended to “eat as little as possible any processed foods and cured meats, reading labels for any nitrates and nitrites, organics, sometimes the water may also be contaminated with nitrates or

Who doesn’t enjoy a BLT sandwich, beef jerky, hotdogs or a nice ham during the holidays, spinach, lettuce and celery? What do all those have in common is the use of sodium nitrates to give the meats its color and flavor all love and natural sodium nitrates found in vegetables. Sodium nitrates prevents bacteria growth and can help to lower blood pressure. Yes there are some concerns and learning all the facts can make sure you make an informed decision when it comes to skipping the ham on the next

Imagine you sprained your leg and it hurts so bad you feel like you can’t even move, Imagine how amazing it would feel to get a cold pack put in your injury, Imagine the pleasure it would give you. I work for the Anaheim Ducks, I create cold packs to help with light injuries. I chose to use Potassium Chloride as my chemical since it had a major decrease than the Sodium Bicarbonate.

Methaemoglobin is a stable oxidised form of haemoglobin which is unable to release oxygen to the tissues, produced in some inherited abnormalities and by oxidising drugs. Normally one or two percent of a persons haemoglobin is methaemoglobin, a higher percentage than this can be genetic or caused by exposure to various chemicals. Amyl nitrite is administered to treat cyanide poisoning. It works by converting haemoglobin to methaemoglobin which allows for the binding of cyanide and the formation of non-toxic cyanomethaemoglobin. Increased levels of methaemoglobin are found in blood stains. Upon exiting the body, bloodstains transit from bright red to dark brown which is attributed to oxidation of oxyhaemoglobin to methaemoglobin and

In an acidic environment nitrite, can react with aromatic primary amines and form diazonium ions. In this case, sulphanilamide will be used. When the diazonium ions react with a coupling reagent a pink coloured azo dye is formed. There is a quantitative relationship between the nitrite ions and the azo dye, assuming complete reactions where the coefficient ratio is 1:1, then all the nitrite will turn into the azo dye. The absorbance of the pink dye is found with a spectrophotometer (Mygind, 1991). By using Lambert-Beer’s law and a standard curve the concentration of nitrite can be found when the absorbance is known.

Amyl Nitrates, also known as “Poppers,” were created in a lab in the year of 1857. The original use of Amyl Nitrates were to ease chest pain and also ease pain from Angina. When the drug was first manufactured in small glass containers that made a popping sound when the capsules were opened, hence creating the nickname, “Poppers.” Not even two years later, the first effects of the drug surfaced, being noticed by doctors in Europe. Then, eight years later, doctors learned about how the drug made the user feel relaxed, because of the effect it had on the user’s muscles. Upon the success of how it helped ease pain from Angina and other pains, the FDA approved Amyl Nitrate as an over the counter drug. However,

After exposing the sample to UV radiation the visible band is determine to be at the maximum absorbance, as shown in Figure 1. This absorbance band at 563 nm and 579 nm corresponds to the reaction SP → MC. By monitoring the exponential decay function of MC, we are able to construct a linear fit of the data, as shown in Figure 3, which confirms a first-order decay. The corresponding rate constants were determined from the slope of the fit, and it was found that as we increase [SP] the rate is relatively constant. Further, this reaction was done on different solvents, which includes acetone and cyclohexane. Following Table 2, it seems that with the addition of cyclohexane, the rate of decay of MC is faster. This indicates that due to the non polar

Lysergic acid diethylamide is a psychedelic drug responsible for causing hallucinations and mood altering behavior. It is manufactured from the lysergic acid found in the ergot fungus found on the grains like rye. It is manufactured in crystal form and is mostly used as a recreational drug. LSD is either swallowed or kept under the tongue and it is odorless, colorless and bitter in taste.Thankfully this drug is not addictive but can have mental side effects like delusions, panic attacks,depression and

However, nitrate reductase can further reduce nitrite to ammonia or molecular nitrogen, which does not react with the reagents and does not produce a colour change. To verify nitrate has been reduced past nitrite, zinc powder is added to the medium. If the medium does not change colour after the addition of zinc powder, then the nitrates in the medium have been reduced further. If the bacterium does not use nitrate, then the addition of zinc powder will reduce the nitrates in the medium to nitrite, changing the medium to a pink or red colour.

IV medication may include giving the medication by rapid injection (push) into the vein using a syringe; this is called a bolus dose. One additive that must never be given as a direct IV bolus is potassium chloride. Potassium is an essential electrolyte which the body needs to function correctly. Potassium is works on the nerves and muscles in the body including the heart. As important as potassium is having too much potassium can be life threatening. Potassium’s role on the heart is to keep the heart beating at a normal rhythm. A bolus dose of potassium chloride may cause cardiac arrest within minutes if the dose is too high is the medicine is push in too quickly (Australian Prescriber, 2014).
