i do not have any answer,i want the answer
Ethanol is used because the Aspirin can dissolve into it however when it is then added into the water the aspirin can dissolve so comes back and re appears and as it reappears it comes back purer than before
I suppose that for a medical grade acetylsalicylic acid this is not problem.
Recrystallisation, as it is solid at room temperature, but is soluble at elevated temperatures. Distillation requires boiling, so distillation of solid aspirin is not appropriate, in the general sense.
I'm not sure, but when we did a lab about it we discovered that using more water to rinse the solution causes very much Aspirin to be lost in the purification process.
you should use the purification way to purify the water
I would perform distillation on isoamyl acetate for its purification because it has a significantly different boiling point compared to impurities, making it easier to separate. Recrystallization might not be as effective since isoamyl acetate is a liquid at room temperature and may not form crystals.
the water went throught a purification process.
water
if you use it with alcohol.
No.
By repeated evaporation, solubilization and recrystallisation.
There are no interactions listed concerning the use of aspirin with Keppra.
