The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all

Experiment 4: Conductivity of electrolyte solutions (Dated: October 29‚ 2009) I. INTRODUCTION Pure water does not conduct electricity‚ but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound‚ which produces the ions as it dissolves‚ is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly‚ a weak electrolyte dissolves

Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer tablets were first obtained. Vinegar‚ a 250-mL beaker‚ and a 50-mL (or 10-mL) graduated cylinder was given from the instructor. After the experiment‚ a graph of percent by mass of the

SHORT-RUN TACTICAL DECISIONS The organizations strive to earn short-run profits. In making short-run decisions‚ not all cost and revenue data is relevant. The cost data relevant for decision-making is referred to as relevant costs and that which is not useful for decision-making is non-relevant costs. On the revenue side‚ the only relevant revenue is the incremental & differential revenue. Relevant and Non-Relevant Costs: 1. Future Costs and Sunk Costs (IR): A future cost is that cost yet

Ecology is the study of the relationship of between organisms and their environment‚ including both the living and nonliving compounds. Some of the ecological concepts include succession‚ energy flow between trophic levels‚ limiting factors‚ and carrying capacity. First‚ succession is a change in species structure of an ecological community over time. Over time species in the community become more and more abundant and may not be present at all one day. Also‚ sometimes new species might invade the

| Next‚ we used stoichiometry to calculate the necessary mass of reactants to produce about 2 grams of silver: [pic] [pic] The limiting reactant is the reactant in a chemical reaction that limits the amount of the product that can be formed. The reaction will not continue after all of the limiting reactant is consumed. The limiting reactant in our reaction is Cu because we want the entire amount of the element to bond with the AgNO3. The excess reactant is the reactant in a chemical
