Why benzocaine precipitates during the neutralization

It reacts during an acid-base neutralization. A precipitate is a solid formed during a reaction. No, benzocaine is not considered a narcotic. No, benzocaine is an ester. Neutralization is an exothermic chemical reaction and thus heat is given out. Some involve acids and bases and form water in a neutralization reaction. Others produce a gas. A benzocaine is a local anaesthetic used as a topical pain reliever. Salts are formed during neutralization reaction. Not only salt, water is also formed.

Sure you can. But why ruin a perfectly good batch of benzocaine? For Precipitation is the formation of a solid in a solution during a chemical reaction. When the reaction occurs, the solid formed is called the precipitate. There are no specific "conditions".

If the one of the new products formed during the reaction is insoluble in the solution, then a precipitate has formed. Benzocaine is a local anesthetic. It is the active ingredient in over the counter balms and ointments that treat earpain, oral ulcers, chapped lips etc. Benzocaine looks a lot like Cocaine, which is why it is mixed with cocaine during import to make the amount of cocaine imported seem larger. It has nothing to do with getting high or any other reason for it to be made illegal.

Anal ease, which a numbing lubricant used for anal sex, contains a mild anesthetic named Benzocaine. Benzocaine is the same ingredient that is used in the Ambesol. Benzocaine numbs sensitive skin. Benzocaine is a local anesthetic, for which drug screens do not test. Synthesis of benzocaine: Into a ml flask, mix 1. Heat the mixture at reflux for 2 h. When sulfuric acid is initially added to the mixture, p-aminobenzoic acid assumes its zwitterion form, wherein the carboxyl group is deprotonated and the amino group protonated.

As more acid is added, the pH increases and the protons in the solution also increases. Explain why benzocaine precipitates during the neutralization. With the addition of an acid, the amine group on the benzocaine will become protonated. The protonation creates a positive charge on the benzocaine molecule. Thus, the benzocaine will no longer be soluble and will precipitate during neutralization. It establishes comprehensive clinical guidelines to diagnose and manage acute otitis media AOM , as well as when and how to treat signs and symptoms.

It provides a review of multiple research studies and offers recommendations for practice. Its main finding is that watchful waiting is preferable to prescription of antibiotics in treatment of children with uncomplicated AOM.

Block, S. Causative pathogens, antibiotic resistance and therapeutic considerations in acute otitis media. Pediatric Infectious Disease Journal. This is a unfiltered source. It is an appropriate source for nursing practice because it gives in depth overview of pathology on pathogens that are associated with AOM and the medications used in treatment.

On the other hand, it does not address watchful waiting as a mode of treatment; instead it recommends other antibiotics to combat penicillin-resistant organisms. This article is an evidence summary. Kelley, P. Ear, nose and throat. Hay, M. Levin, J. Deterding Eds. Waxman: Here is our strategic plan for our organizational behavior class. Throughout this report we will explain our plan intended to increase financial satisfaction for Colgate- Palmolive.

We sincerely hope that this report will fulfill your expectations, and we assure you that the oral presentation will be a great complement in order to influence the implementation of our ideas. Thank you for your time and consideration, and we look forward to finally present our ideas to you and to our audience. Explain why benzocaine precipitates during the neutralization. With the addition of an acid, the amine group on the benzocaine will become protonated.

Thus, the benzocaine will no longer be soluble and will precipitate during neutralization. Addition of sulfuric acid causes the protonation of the amino and alcohol groups of p-aminobenzoic acid, and eventually the carbonyl group.

In ethanol, this very positive molecule is no longer soluble in ethanol, a relatively non-polar solvent.
