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…

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…

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…

reaction and are formed when cations and anions intermix in an aqueous solution.3 Some reactions vary based on temperature or solute concentration. The determination of precipitates also come from solubility rules. According to Cooper, almost all sodium, potassium, and ammonium salts are soluble which mean that they will not form a precipitate.1 All chlorides, bromides, iodides, and fluorides, nitrates, chlorates, perchlorates, and acetates, and sulfates are also soluble. The only exceptions are…

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 tray. 2.…

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…

INVESTING DIFFUSION THROUGH LIVING MEMBRANES Introduction Cells are living membranes. They are the basic unit of life. They are very unique in that they have the capability of carrying out a large number of chemical reactions in the body, ability to respond to stimuli, capable of producing more of themselves, they have a genetic program and the means to use it, they acquire energy and utilize it, all in the process of the functioning of the human body, The life of a cell is also dependent on…

Grilled Salmon There a variety of methods you can you to cook Salmon; however my best method is to grill it. The natural oils found in the Salmon help it to retain the moisture and also develops some crispiness on the outer side of the fish. Ingredients - 1 ½ pounds of salmon fillets - Lemon - Salt (to taste) - ¼ cup of olive oil - 1/3 cup of water - 1/3 cup of soy sauce - Garlic powder (to taste) Directions You just need a few easy steps to your ideal Grilled Salmon Prep time- 15 minutes Cook-…

(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…
