Although the acetanilide and aspirin are both quite insoluble in water at room temperature‚ the sodium salt of aspirin is very soluble in water but insoluble in dichloromethane. Because aspirin is a reasonably strong acid‚ it can be converted to the salt‚ sodium acetylsalicylate‚ by reaction with the basic sodium hydroxide. While the two layers are thoroughly mixed‚ the aspirin will react with the sodium hydroxide in the bottom layer‚ which then migrates to the aqueous layer and can be easily separated

test was conducted. A change in the strip to a deep blue color would signal an excess of sodium hypochlorite reagent present. An excess is the reagent symbolizes the end of the reaction because there is no longer any reactant left to consume reagent. After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as an oxidizing agent‚ the starting diol and final product were characterized

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

The diet focuses on foods rich in fruits‚ vegetables‚ low-fat dairy products‚ whole grains‚ fish‚ poultry‚ beans‚ seeds‚ and nuts. It is low in salt and sodium‚ added sugars and sweets‚ fat and red meats. American Diabetes Association suggests a diet that is high in fiber instead of one high in protein. Of all three sites none recommend a diet high in protein. 3. Any race can be affected with kidney disease

Within our global economy‚ we are bombarded by companies advertising schemes informing consumers the product is healthy and nutritious. This clouds our perception of what is a “healthy” food and how much we should consume of that food. After spending eight days analyzing the food I consume‚ including the homemade items‚ I find much of the food on the market today is a potentially toxic form of poison hidden under a bunch of government politics. Prior to this class I was under the influence of many

HYPOTHESIS / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any chemicals; consequently the ions must combine in definite ratios. EXPERIMENTAL DESIGN A technique is performed in which copper (II) sulfate and sodium carbonate are placed together in various test tubes‚
