Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…

Solutions should be the cations of cupric nitrate, ammonium nitrate, zinc nitrate, calcium nitrate, aluminum nitrate, silver nitrate, ferric nitrate, and plumbous nitrate. The other seven solutions should be the anions of sodium hydroxide, sodium carbonate, potassium sulfate, sodium iodide, sodium phosphate, sodium chloride, and sodium chromate. Divide students into groups of two. Provide a bin of paper towels for the students to empty their well plates. Students: Obtain a pair…

Part A Results We hypothesized that the iodine will diffuse into the bag, turning the inside a darkish blue/black color. We also hypothesized that glucose will diffuse out of the bag, forming a green color (after the Benedict’s test). This experiment was set up using a dialysis tubing bag, balloon clips, beaker, iodine, solution of 1% soluble starch and 15% glucose. The dialysis tubing bag was filled up with starch and glucose, leaving a pocket of air for diffusion of materials, and sealed…

Observations: This experiment was divided into two parts: one part was to observe the properties of a single Alka Seltzer tablet and the second part was to find the percentage of CO2. In the first part of the experiment, the visible properties of Alka Seltzer were observed and recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate. Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking…

The way that they identified was to measure the pH first. There was only a one strong base which was #66, so it was 1 M sodium hydroxide. And then there were two very strong acids, one of them didn’t show any visible reaction which is #65, so it was 1 M nitric acid, which means #60 was 1 M hydrochloric acid. #61 was a strong acid that didn’t react with any of the other solutions,…

purpose of this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium carbonate • 8 bottles of unlabeled chemicals the same contents as known chemicals • 1 well tray Procedure 1. Place 7-10 drops of each chemical (known and unknown) into separate wells in the well…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

The purpose of this experiment was to determine the identity of nine solutions using the results of reacting pairs of solutions in an organized systematic manner. Known solutions were used on the first day. The second day, the solutions were placed in code-labeled bottles. The reactions from the previous day were then used to help identify which solutions were which, by closely monitoring which unknown solutions mixed with other unknowns and how they reacted, such as: color changes,…

(Un) substituted-2-phenyl-4H-3, 1-benzoxazin-4 one (1, 2) was converted to 3-amino-2-phenylquinazolin-4(3H)-one and its substituted analog under reflux for 6-7 hr with hydrazine monohydrate in ethanol. The concentrated solution was poured into ice cold water to obtain a solid product. The obtained solid was washed with water, filtered, dried and recrystallized from ethanol1. Synthesis of 3-(benzylideneamino)-2-phenylquinazolin-4-(3H)-one 5 (a-j) A mixture of 3-amino-2-phenyl-3H-quinazoline-4-one…
