Aspirin (acetylsalicylic acid) is a very well-known drug. It exists as a “ionic form” that melts well in streams. But when protonation occurs, it is It can pass through cell membranes and inhibit certain chemical reactions.
In the above technique, complete the chemical reaction equation of the aspirin “neutral form” to “ionic form” reaction.
Homework Answers
We know that aspirin is a drug. It is otherwise known as acetyl salicylic acid.
The neutral form of aspirin undergoes protonation to become it's ionic form. The reaction can be written as:
C6H4OCOCH3COOH + OH− -----> C6H4OCOCH3COO− + H2O

Mustrates treat all types of ilnesses. Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the andient Greeks as a treatment for pain and fever. Salicylic acid (and many related phenols) are very hard on your Ho stomach, but when esterified, as aspirin is, they are much better tolerated. Simple esters are...

A well-known symbiotic relationship exists between ants and acacia trees. The plant produces specific sites where food is provided for the ants, and in return the ants protect the plant from herbivores. If an herbivore makes the mistake of “messing" with the acacia, the ants swarm upon it, stinging and biting, soon making the herbivore wish it had never taken a bite. A newly discovered relationship on the acacia involves the only spider species known to be an herbivore. The...
