Synthesized Methamphetamine was first synthesized from ephedrine in Japan in 1893 by chemist Nagai Nagayoshi. In 1919‚ crystallized methamphetamine was synthesized by Akira Ogata via reduction of ephedrine using red phosphorus and iodine. Synthesis is relatively simple‚ but entails risk with flammable and corrosive chemicals‚ particularly the solvents used in extraction and purification; therefore‚ illicit production is often discovered by fires and explosions caused by the improper handling

Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

First‚ the synthesis of the coordination compound‚ KaFeb(ox)cdH2O‚ needed to be carried out. This was achieved by weighing out 8.29 grams of K2C2O4 with a Dial-a-gram balance. Once measured‚ the 8.29 grams K2C2O4 were placed in a 125 mL Erlenmeyer flask. 25 mL of deionized water were then added to the 125 mL flask and stirred with the K2C2O4 until complete dissolution was achieved. Next‚ 4.11 grams of FeCl3 were weighed out using the balance previously mentioned. Once the 4.11 grams were measured
