Question

Assume that 1g of aspirin dissolves in 450 ml of water at 10 degrees celsius, how much aspirin would be lost in the 1.5 ml of water added to the reaction mixture if the mixture were at 10 degrees during filtration

Answer 1

Aspirin is acetylsalicylic acid with chemical formula C₉H₈O₄. This is an anti-pyretic drug used to treat pain, fever, or inflammation. Aspirin contains polar functional group i.e, carboxylic acid group (-COOH) which can form hydrogen bonds with polar water molecules and gets dissolved.

450 ml water can dissolve 1g of aspirin, so, 1.5 ml water can dissolve
`(1.5X1)/(450) g`= 3.33 x
`10^(-3)`

So, 3.33 X 10⁻³ g of aspirin would be lost in the 1.5 ml of water.
