NaHCO 3 ( s )Na 2 O ( s )+H 2 O ( g )+CO 2 ( g) Reaction B. sodium bicarbonate. Wash the beaker and the funnel with 5 to 10 mL of water. Rinse the crystals several times with small portions (5 mL) of cold water and air dry the crystals on a Buchner funnel by suction until the crystals appear to be free of solvent. This will cause the precipitation of the acetylsalicylic acid and will react with any remaining acetic anhydride. Inactive ingredients none Questions or comments? When it reacts with water, we end up with two products, salicylic acid and acetic acid. Question: (1) Write the balanced equation for reaction of: (a) aspirin with aqueous sodium bicarbonate. In this section are described differences between general extraction procedures and the process as summarized in Figure 4.59. Call your doctor for medical advice about side effects. Due to its acidic nature, benzoic acid can undergo a reaction with \(\ce{NaOH}\) as follows, resulting in the carboxylate salt sodium benzoate. Aspirin can cause false urine glucose (sugar) test results if you regularly take 8 or more 324-mg, or 4 or more 500-mg (extra-strength), tablets a day. Do not double doses. Now that you are familiar with the mechanism of the hydrolysis of aspirin the following activities are designed to deepen your understanding of the mechanism and apply the knowledge to the hydrolysis of other esters. Esters are usually derived from carboxylic acids. Add 5 mL (0.05 mole) of acetic anhydride, followed by 5 drops of conc. At a higher pH in the intestine (pH = 6), a greater proportion of aspirin is ionized, so it moves across membranes slower. Use a thermometer or other temperature probe to record the initial temperature. It may be used to treat the symptoms of stomach or duodenal ulcers. In this manner, a mixture of benzoic acid and cyclohexane can be separated (Figure 4.54b). All rights reserved. Analgesics are compounds used to reduce pain, antipyretics are compounds used to reduce fever. Smaller amounts or occasional use of aspirin usually will not affect the test results. The sodium chloride product will then be carefully retrieved, dried and weighed at the end of the reaction. The -OH group from phenol on the salicylic acid condenses with the carboxylic acid group of acetic acid forming acetylsalicylic acid. The structures of the products of the acid catalyzed hydrolysis of each of the esters are given below. Additionally, the sodium bicarbonate neutralizes the catalytic acid in this reaction. This may increase the chance of side effects during treatment. Aspirin with sodium bicarbonate The conjugate base is a salt and is water soluble; therefore, it is removed from the organic solvent layer. Ronald received his PhD. Lower concentrations of \(\ce{HCl} \left( aq \right)\) are less hazardous, but increasing the volume of the aqueous layer by a large amount would affect the efficiency of subsequent extractions and filtering steps. Aspirin (acetylsalicylic acid) is an aromatic compound containing both a carboxylic acid functional group and an ester functional group. R-COOH + NaHCO3 R-COO (1-)Na (1+) + CO2 Acetanilide Structure & Formula | What is Acetanilide? \(\ce{RNH_2}\)), and neutral components to be purified through a series of extractions, as summarized in Figure 4.59 (which uses an organic solvent less dense than water). In an aqueous solution, aspirin is known to undergo decomposition by hydrolysis into salicylic acid, and the decomposition reaction is promoted at high temperatures, in alkaline solutions, and in the presence of magnesium. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines. It is also called acetylsalicylic acid, derivative of salicylic acid, that is a mild nonnarcotic analgesic (pain reliever) useful in the relief of headache and muscle and joint aches. Under room temperature conditions, it would take nearly a month for all of the aspirin to be degraded. This reaction can occur with acidic or basic conditions. The synthesis of aspirin is known in organic chemistry as an esterification reaction.
