Ammonia production

RESULTS & DISCUSSION The unknown solution of metal nitrate salts was identified to contain silver (Ag+) and Calcium (Ca2). These cations were discovered through a qualitative procedure that systematically separated the unknown ions from the solution by introducing known reagents and observing the resulting reaction that presented characteristic chemical properties unique to each cation. These observations guided the flow of the procedure, with the expected results of each step accumulating to justify

Analysis of Silver in an Alloy Introduction In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid, the silver will be precipitated as silver chloride, and the silver chloride will be filtered, washed, dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample, you will be able to calculate the percent of silver in the alloy. Because the results are

This section of the experiment was composed of a series of different chemical reactions. In the first reaction, a small piece of zinc is placed is in a test tube that contains 2 mL of 6 M HCl; observations were then recorded. The next reaction, which should take place under a hood, requires a 1-inch copper wire to be placed in a clean test. Concentrated nitric acid is then added and observations are recorded. In the third reaction, 1 mL of 0.1 M sodium oxalate, Na2C2O4, is placed in a clean test

This experiment is dived into five cycle steps. The first step of the cycle was the reaction of copper when it reacted with nitric acid forming reaction one. As this reaction occurred, I observed how the beaker started to bubble, the sides of the beaker turned yellow at first then it vanished immediately turning the solution light blue. The fume vaporized as the copper started to dissolve. The reaction occurred in step one was double replacement. The second cycle included sodium hydroxide as the

Gravimetric Analysis: The Determination of Phosphorus in Plant Food Gravimetric analysis is a quantitative (i.e. how much?) method of classical analysis. The element to be determined is isolated in a solid compound of known identity and definite composition. The mass of the element that was present in the original sample can be determined from the mass of this compound. Plant foods contain three essential nutrients that are not readily available from soils. These are soluble compounds

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids, bases, and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH, the strong bases that have the highest pH, and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

Gravimetry is an old technique which has been used for the determination and recovery of gold ever since its discovery. It is a process that has a minimal room for instrumental error and does not require standards for any calculation of the unknown that is being analyzed. The determination of gold besides gravimetry can either be titrimetry or instrumental, but these techniques requires gold standards for comparison of its results and concerns the determination of gold in small scale or trace amounts

Synthesis of Isopently Acetate (Banana Oil) Deborah Nyabando CHEM 2311 TA: Nicholas Serratore February 20, 2014 Purpose: The purpose of doing this experiment was to prepare isopently acetate, an ester that has a pleasant smell like that of bananas from isopently alcohol and acetic acid by the Fischer esterification reaction. Sulfuric acid was used as a catalyst. Water, sodium bicarbonate, and sodium chloride were used to extract any impurities from the product. Simple distillation was then used

coli, another undisclosed truth comes to light in this documentary. To get rid of the E. coli, our meat products are thoroughly cleansed with ammonia. Ammonia is a chemical that most Americans recognize as a household cleaning item, and now this chemical is in our meat. We are being secretly exposed to this chemical and it is not even guaranteed to work 100% of the time. However, this is not the only
