Answer #1

carboxylic acid anhydrides are compounds that formally consist of two condensed carboxylic acid molecules.

By heating of two molecules of a carboxylic acid in such a way as to remove or extract (from them) one molecule of water, an acid anhydride may be formed

Consider the preparation of acetylsalicylic acid (aspirin), by reacting salicylic acid with acetic anhydride. A reaction was performed in which 2.05 g of salicylic acid was reacted with an excess of acetic anhydride in the presence of phosphoric acid to make 1.82 g of acetylsalicylic acid (aspirin). Calculate the theoretical yield and percent yield for this reaction.

Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2). The balanced equation is C4H6O3+C7H6O3→C9H8O4+C2H4O2 In a laboratory synthesis, a student begins with 2.80 mL of acetic anhydride (density=1.08g/ml) and 1.24 g of salicylic acid. Once the reaction is complete, the student collects 1.21 g of aspirin. Part A) Determine the limiting reactant for the reaction. acetic anhydride or salicylic acid Part B) Determine the theoretical...

A laboratory procedure is used to measure the level of cadmium in soil. It is applied to a specimen that has a controlled level of 1.5 μg/g of cadmium. Three measurements are obtained by splitting the specimen into three parts of equal weight and applying the procedure to each part. Here are the results: 1.64, 1.85, and 1.94. (a) Does a 95% confidence interval give an indication that the laboratory procedure may be biased? b. What are your assumptions that...

1. How many moles are in 9.6 mL of acetic anhydride, density of 1.082? Give two significant figures. Given molecular weight: 102 g 2. As a "rule of thumb" there are 20 drops of a liquid in a mL. Using this estimate and a density of 1.685, how many moles are in 9 drops of 85 % by weight phosphoric acid? Give two significant digits. Given molecular weight: 98 g 3. Starting with 9.6 g of salicylic acid, how many...
