caffeine and hydrochloric acid
Homework Answers
C8H10N4O2+ HCl ----> C8H11N4O2Cl
Caffeine is an akaloide, meaning it is bearing amine like nitrogen atoms in its molecule and thus supposed to react as a base in aqueoussolutions.
Nitrogen is sp2 hybridised. Therefore, it will react with HCl. A simple acid- base reaction will take place, yielding C8H11N4O2Cl is formed followingbreaking of double bond of that Nitrogen (Caffeine + H+ ---> [CaffeineH]+) Refer to: http://en.wikipedia.org/wiki/File:Caffeine.svg tocorrellate.
Please let me know if you need me to further explain! Good luck!!

In a lab, we seperated Excedrin (paracetamol, acetylsalicylic acid, caffeine, and binder). First we dissolved the powder in diethyl ether. This seperated the mixture into caffeine/acetylsalicylc acid and binder/paracetamol. K2HPO4 was added to the caffeine/acetylsalicylic acid. Give the reaction mechanism for K2HPO4 + caffeine and K2HPO4 + acetylsalicylic acid. HCl was then added to K2HPO4 + acetylsalicylic acid. Give this reaction mechanism.

7. The solubility of caffeine in water can be altered by adding hydrochloric acid (HCI) to the solution. In the presence of a strong acid, caffeine takes on a proton to produce a conjugate acid. The conjugate acid of caffeine is a charged ion. Explain whether you think the formation of this charged caffeine ion increases or decreases caffeine's solubility in water. The cat in Hornaises

1)-Briefly explain the role of the hydrochloric acid during the liquid-liquid extraction procedure. Draw the acid-base reaction between lidocaine freebase and hydronium chloride to help your discussion and circle the organic species that is more soluble in water. 2)- Briefly explain the role of the potassium hydroxide during the liquid-liquid extraction procedure. Draw the acid-base reaction between lidocaine hydrochloride and potassium hydroxide to help your discussion and circle the organic species that is would be more soluble in the organic...
