How many milliliters of boiling water are required to dissolve 25 g of phthalic acid? If the solution were cooled to 14 degree Cellucius, how many grams of phthalic acid would recrystallize out?
Don't you have a table giving the solubility of phthalic acid at 25C and 100 C? I don't have those numbers memorized.
