specific unknown compound. These tests included a solubility test, which determines whether the compound is soluble in water, a pH test to determine the relative acidity of the compound, and a flame test, which shows the presence or absence of metal ions, and an anion test. The compound was then tested with five other known compounds to provide more evidence of the true…

Free radicals form when weak bonds split. They need to be stable so they react very fast with other compounds. When the free radical attacks a molecule, it takes an electron, which turns that molecule into a free radical. It is like the domino effect. The body may also create free radicals on its own. It creates them in small amounts so it’s not very harmful to the body. Harmful things in the environment will also create them. The body is only able to handle a certain number of free radicals…

Hydrogen Cyanide Hydrogen Cyanide (HCN) is an extremely poisonous liquid discovered in 1782 by Carl Scheele, a Swedish chemist. HCN is very toxic because it stops cells from using oxygen properly thus causing death. Although HCN is a great solvent for salts, it cannot be used due to its high toxicity. Even though it is general stable, it has the capacity to combust in the company of basic substances such as ammonia or sodium cyanide. What is its structure? The structure of Hydrogen cyanide is…

The Identification of an Unknown Substance Using a Series of Tests Project 2 Chemistry 111 – 552 Peyton Farmer*, Primary Author Partners: Jacob Hicks and Abigail Boudreau TA: Ming Uei Hung Introduction The purpose of this experiment was to use elimination and confirmation tests for both cations and anions, which then allowed the unknown substance to be identified by using logic trees of known solutions. Some qualitative characteristics of chemicals such as the formation of a precipitate, the…

will attract other charged particles such as ions and other polar molecules such as glucose. Therefore chemical reactions can take place in solution since these chemicals dissolve in water. For example when you pour a salt (NaCl) into a cup of water, the molecule NaCl which is bonded ionically will separate into sodium ion (Na+) and chloride ion (Cl-). This is because the negatively charged oxygen atoms in the water molecules attract each of sodium ion and the positively charged hydrogen atoms…

behaviors of different concentrations. Household items were used to help apply basic theories about acids and bases such as pH. The titration curves were evaluated to help determine which indicator needed to be used for the indicator titration. Anions are ions that have more electrons than protons, therefore,…

Chemistry relates to everything you could possibly think of on the planet. They relate to every object and every natural event and hazard. Such as sinkholes, there a very intimidating and scary event that could happen at any moment . Sinkholes occur when the limestone beneath us breaks away by acidic rain and eventually the ground gives creating an open hole in our earth`s surface. Chemistry can relate to chemical reactions, one of the chemical reactions that occur is the creation of acidic rain…

Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved…

CH 204- Introduction to Chemical Practices Experiment 1- Qualitative Analysis of Cations Sharon Alexander Kathrynn Labat TA: Yu-Chun Lin September 25, 2017 Results & Discussion This experiment was composed of three parts. In the first part, qualitative methods were used to identify the unknown cation in an aqueous solution. The cation was to be either lead or silver. If silver was present, extra steps were needed to be taken in order to confirm its presence in the…

In Co(NH3)6Cl3, since the complex has a total charge of zero, ammonia has an oxidation number of 0, chlorine has an oxidation number of -1, cobalt has an oxidation number of +3. Therefore, there are four electrons in the d orbital of a cobalt in this complex. Figure 8 gives the possible high spin and low spin combinations for four d orbital electrons. The high spin config- uration has four unpaired electrons and the low spin configuration has two unpaired electrons. Figure 7. High and low…
