Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

The Dumbest Generation Synthesis Essay In the modern world of today‚ the Web is the medium of all information. It is how information is transmitted and created. It’s how information is viewed and immortalized. Why is it then‚ that the Web is making today’s generation “dumber”? It does feel as if we‚ this current generation of people‚ are becoming more blunt and dull. Many professors and scholars point the cause to the our carefree lifestyle‚ the web‚ and the furthering advancement of technology

acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together‚ and then acidified by the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation was salicylic acid. After

purpose of this essay is to discuss the Islamization of Persia in relation to the Samanid and Buyid Dynasties. The synthesis of Persian culture and Islam was not an immediate result of the Arab expansion into Iran and there is certainly a lack of research on the subject. However‚ in this essay‚ I will attempt to explain the contributions of the Samanid and Buyid dynasties to this synthesis with a focus on the attempts of the Samanid Dynasty at centralization and a unified identity through religion‚ language

particularly fruit flavors -- have just one or a few dominant chemical components that carry the bulk of the taste/smell signal. Many of these chemicals are called esters. Esters have the structure of -COOR. Instead of the alcohol portion of thecarboxylic acid (-COOH)‚ there is an ether portion. The low boiling‚ volatile esters are known for their "fruity" smell and flavor. They are used in artificial flavorings. (Operational Organic Chemistry‚ John W.

and acetic anhydride were used to create acetaminophen and acetic acid. The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure sample was 76%. The melting point of the pure sample was 167C - 169C. Introduction: Formulation of acetaminophen involves treating an amine with an acid anhydride to give rise to an amide. In this experiment‚ p-aminophenol

Microwave Synthesis of 5‚10‚15‚20- Tetraphenylporphyrin Abstract: In this green chemistry experiment of 5‚10‚15‚20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole. using microwave irradiation to heat the reactants.‚ The liquid reactants are absorbed on a solid support‚ silica gel‚ which acts as a Lewis acid catalyst to facilitate the reaction. The reaction forms a porphyrinogen‚ which is then oxidized to the porphyrin product by atmospheric oxygen. Column chromatography is performed

Education Synthesis Essay Read the following sources carefully. Then write an essay that develops a position on whether or not there should be specific texts all students of high school English must read. Synthesize at least three of the sources or support. Have you ever wondered how life would be if everyone learned the same thing? Seems like we’d all be pretty equal‚ living with the same knowledge. In high school‚ it seems logical to read the same texts in all English classes. The canon
