DQuestion 3 2 pts In lab, you add 2.07 g salicylic acid to a 125 mL Erlenmeyer flask, as listed in the procedure. You carefully add 4.0 mL acetic anhydride and have your TA add 5 drops of sulfuric acid After completing the synthesis and filtering. you place the crystals to dry on an evaporating dish that weights 21.616 g. After drying, the crystals and evaporating dish weigh 23.404. Calculate the percent yield of aspirin Insert the value as a...

You are asked to prepare 500. mL of a 0.100 M acetate buffer at pH 5.00 using only pure acetic acid (MW=60.05 g/mol, pKa=4.76), 3.00 M NaOH, and water. Answer the following questions regarding the preparation of the buffer. 1. How many grams of acetic acid will you need to prepare the 500 mL buffer? Note that the given concentration of acetate refers to the concentration of all acetate species in solution. 2. What volume of 3.00 M NaOH must...

acetic acid is 25 ml and alcohol is 20 ml
The synthesis of an ester by the reaction of a carboxylic with an alcohol is an equilibrium reaction. H - R-OH HO ROH R OR, Recall from general chemistry that, according to Le Caiclista principle, an equilibrium can be shifted toward greater product formation by using an excess of reactant or by removal of a reaction product as it forms. 1. Are any products removed during the reaction period (the...

You may attempt this question 2 more times for credit. Note that carboxylic acid is used in slight excess (mol alcohol + 0.001 mol). To synthesize 0.018 mol of 3-methylbutyl pentanoate, grams, or of 3-methyl-1-butanol and grams, or mL of pentanoic acid are needed. MW of 3-methyl-1-butanol = 88.2 g/mol density of 3-methyl-1-butanol = 0.809 g/mL MW of pentanoic acid = 102 g/mol density of pentanoic acid = 0.939 g/mL CHECK ANSWER
