Making Aspirin more soluble
« on: November 05, 2005, 01:04:15 AM »
I got this one question to do for my h/w....

1)How could I make the structure of aspirin more soluble??


add more -OH groups??

ive done some research and ive just come up with calcium carbonate but how would that fit into the chem structure??

would be very grateful if anyone can *delete me*

Aspirin or acetylsalicylic acid can be made more soluble by neutralizing it with a base of Na or Ca. This will create an ionic salt that is more soluble because it has more ions. Physical modifiation will alter the properties.

Ionic compounds are usually more souble in water than they are in [a relative organic solvent], however, the overall polarity strength of a molecule may overcome this ionic trend. But from experience the asprin should follow the trend nicely.
