Answer #1

Solution:

Water mix with ethanol

All the given compounds are polar in nature. Thus, they all are soluble in polar solvents like mixture of water and ethanol. Compounds like acetaminophen is less soluble in water but it is highly soluble in the mixture of water and ethanol.Salicylic acid and acetyl salicylic acid are insoluble in cold water but its solubility increases when it is dissolved in water mixed with ethanol.

    please answer all parts I am trying to check my answers. Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...

    than other labs. These are toxicity, volatility, and flammability. We routinely use toxic organic solvents like methanol and acetone that are volatile (have low boiling points), but even solid organic materials can produce vapors that may be toxic. Furthermore, organic materials are flammable, and solvent vapors in the air can and do produce explosive mixtures. You should take some general precautions when doing organic chemistry: Do not get solutions on your skin. You do not need to always wear gloves...
