Final Solution

added, as well as 10 mL of buffer solution, 1 mL MgEDTA, and 5-6 drops of Eriochrome Black T indicator. The initial volume of the EDTA in the burette was recorded and then the titration started and continued until the sample solution changed colors to pure blue, all the while the solution was stirred. Near the endpoint, the EDTA solution was added dropwise to ensure that the correct final volume was indicated. Once reached, the final volume of the EDTA solution in the burette was recorded and…

for the experiment. Then an analysis of the final product using proton NMR as well as IR should be performed to determine the purity of the final product (melting/boiling point can also be used) and if possible any possible side products that may have been produced should also be identified. Introduction: A catalyst is a compound that increases the rate at which a reaction occurs and…

For years, Nazi Germany camouflaged its merciless and evil vendetta with the face of a harmless recovering nation. However, the outside world wasn’t the only one fooled by the deceitful Nazis. The German people were also sold lies – embezzled futures were promised without the intention of fulfilling their word. The 1936 Summer Olympics in Berlin and heavy propaganda before World War II served an important role in winning over the majority of the German people and created a worldwide positive…

called the Copper Cycle. The initial and final mass of the copper were measured and percent recovery was calculated to demonstrate that mass wasn’t created or destroyed. The balanced equations, balanced formula-unit equations, total ionic equations, net ionic equations, and half reaction equations were also determined for their appropriate reactions. In the first step of the cycle, a copper wire was dissolved by reacting it with 16 M nitric acid. A green solution was formed when the nitric acid…

It was 8:30 on a bitterly cold morning on a November day in the city of Munich. Hitler and his storm troops assemble to surround the beer hall. As Hitler sees the storm troopers gathering around the facility, he decides that this is the perfect time for his putsch or “national revolution”. He enters the beer hall and fires his weapon. “BAM!” The blast of the loud firearm shocks the crowd tremendously and they freeze to see what Hitler will do next. He takes the speaker of the large crowd, Von…

All living systems contain buffer solutions to sustain the structure and activity of biological components such as DNA, RNA, proteins, carbohydrates, and lipids. Buffer solutions are remarkably resistant to pH changes and generally consist of a weak acid and its conjugate base or a weak base and its conjugate acid. In the laboratory, artificially made buffers are often used to help maintain a biological system at the proper pH. A laboratory buffer should be inert in the system being studied.…

sources. (source) Solubility rules state that nitrate salts are soluble in water, and silver nitrate is no exception. When the soluble silver (I) nitrate salt solution is combined with the soluble sodium chloride salt solution, a white precipitate of silver (I) chloride is produced. (Source) Silver can also be dissolved using thiosulfate solution. However, studies have shown that the resultant AgNO3 electrolyte is considered to be ideal for further silver recovery via electrolysis or…

Decision making tools are a vital aspect of the business industry. Such tools and processes afford managers in the healthcare industry and other business entities the opportunity to systematically evaluate a problem, find a solution, and evaluate the effectiveness of the end result. The purpose of this paper is to compare and contrast two different decision making processes and elucidate the steps involved that are currently being utilized to determine the need for expansion of a new chest pain…

After the U.S. entered the war though, the immigration numbers decreased. This was also at the time when the Nazi party began to murder the Jews in Europe. After all, more than 200,000 Jews found refuge in America. U.S. reaction to Hitler’s “Final Solution” In 1942, the State Department received a letter sent by the World Jewish Congress. The report said that the Germans were going to apply a policy to destroy all of the Jews of Europe. Officials of the department did not forward the message…

History textbooks only briefly explain the Holocaust without entailing the brutal experiences the Jews had to face every day of their lives. People need to be informed of the legitimate terrors that took place in and out of the camps so history doesn't repeat itself. The Holocaust eliminated Jews by lethal experiments, death camps, and destruction of Jewish societies. Why the Jews were Targeted “If they (the Jews) bring about another world war, they will experience their annihilation. Since…
