Purpose: The purpose of this experiment was to determine the percent of chlorine in an unknown soluble salt through using gravimetric techniques. The unknown salt was dissolved in water and the chloride ions were precipitated using silver nitrate which produced silver chloride. The silver chloride was then separated by filtration techniques and through this the amount of chlorine in the original salt was able to be calculated. It is expected that the chlorine percent will be around 55.95%…

Cl- has the common ion sources of HCl and CaCl2 in test tubes C and D. Le Chatelier’s Principle explains that adding Cl- as a reactant will shift the equilibrium to the right to produce more product from the added reactant in test tubes C and D. When adding acetone to…

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…

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,…

Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured. Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these…

added to the precipitate, forming a solution possibly containing lead (II) ions. A lack of precipitate formed denied the presence of silver ions. Then, K2CrO4 was added to the solution, forming a yellow precipitate to confirm the presence of Pb2+ ions in Unknown #112.…

Potassium hexacyanoferrate (III) complex has octahedron geometry, and the ions are kinetically unstable due to dissociation in the solution. It also has monoclinic and orthorhombic crystals showed only one doublet on the spectrum in phases of high and low temperatures. The compound has photosensitive characteristics, it possesses bioelectric chemical properties, but they are poorly oxidized by common oxidizing reagent. The polytype of K3[Fe(CN)6] are discussed in reference to cobalt salts by…

distributed between hydrogen and oxygen. 10. An ion is a molecule or atom that gets either a negative or positive charge as a result of it losing or gaining one or more of its valence electrons. An ionic bond has an electrostatic force between oppositely charged ions in an ionic compound which affects the chemical link between two atoms. An ionic bond is formed when an electron is essentially transferred from one atom of a pair to the other creating ions. A sodium atom transfers an electron…

order to know more about nitrate, we actually must understand what a polyatomic ion is. A polyatomic is an ion which consist of molecules, thus, it may also be referred as a molecular ion. Two or more atoms covalently bond or share electron pairs with each other to make up a polyatomic ion. Once they have bonded, they become considered as a whole single ion. Moreover, it is known to have a charge, most polyatomic ions have a negative charge but there is an exception with a positive charge. In…

contaminate environment by releasing, but are aquatically toxic. Synthesis:- The methylimidazolium and pyridinium ions have proven to be good starting points for the development of ionic liquids. Properties, such as melting point, viscosity, and solubility of starting materials and other solvents, are determined by the substituents on the organic component and by the counter ion. Many ionic liquids have even been developed for specific synthetic problems. For this reason, ionic liquids…
