Question

I understand that the ester group in an aspirin molecule is released to acelytate the OH group on COX but what does the carboxylic acid do?

Answer 1

-COOH group makes it water soluble by hydrogen bonding

Answer 2

Lancenigo di Villorba (television), Italy ===> question What are each and every of the sensible communities in aspirin? ===> DEBATE Aspirin is the main renowned pharma-drug to defeat indications of hassle-free wintry climate's Flu ; this call is an indicator invented via BAYER Chemical employer already in 1899 and it nevertheless survives becaus of its huge action on human immunitary equipment. Felix Hofman (a swiss chemist) became into the technician who appointed the 1st effective syntheses of here compound ...HC=CH...,..O ...,./...,...,....,..// HC...,...,.C--C ...,...,...,//...,.. ...HC--CH...,.OH ...,...,...,| ...,...,...O ...,...,..., ...,...,...,C=O ...,...,...,/ ...,...,.CH3 which takes names as 2-Acetoxy-Benzoic Acid or ACETYLSALYCILIC ACID. the 2nd call is the popularized one because of the fact it retains for an prolonged time whilst chemists regarded for a chemical waiting to replicate anti-fever action attributed via italian professor R. Piria to acids extracted via Willows' Bark ; S. Cannizzaro (Piria's scholar) became into the 1st to perceive SALYCILIC ACID however the french C. Gerhardt reached to first ever samples of AcetylSalycilic Acid. ===> CHEMICAL sensible group whilst reader come back to Molecular shape drawn few rows in the past, it has to spotlight that the molecule : ---> identifies its nucleus as an Hexatomic middle, e.g. Benzenic Ring ; ---> the Benzenic Ring binds promptly an Oxygen's atom, then the molecule is a PHENOLIC spinoff ; ---> the referred to Oxygen's atom binds in its turn an Acetylic group (CH3CO), now reader has to look the molecule as an ACETIC ESTER ('CH3CO' instruments 'O' to furnish 'CH3COO' or ACETOXY group) ; ---> finally, the Benzenic Ring bonds promptly additionally a Carboxylic group (COOH), now the reader states that the compounds looks like a by-product OF BENZOIC ACID ACIDIC COMPOUND too. i'm hoping this facilitates you.

Answer 3

COO-Na+ of aspirin solubilizes the compound in water so that it goes where it is going.
