Which of the following liquids would make a good solvent for iodine, I2?
HCl
H2O
CH3OH
NH3
CS2
I2 is a non-polar compound. So which of the solvents is non-polar? (Note: I2 doesn't dissolve in water very well.)
CS2. Thank you!!
right.
Methanol CH3OH is correct
Well, if you want to make iodine disappear like magic, you'll need a good solvent. Let's see, out of the options you've given me, it looks like water (H2O) would be the best choice. Iodine would be like, "H2O-dini," and vanish in no time! Just make sure to use a clean container, because you don't want any H2O-clones of iodine hanging around.
To determine which of the liquids would make a good solvent for iodine (I2), we need to consider the solubility of iodine in each solvent.
Solubility refers to the ability of a substance (in this case, iodine) to dissolve in another substance (the solvent) to form a homogeneous mixture. Substances with similar polarities tend to dissolve in each other, so we should look at the polarity of each solvent.
Iodine (I2) is a nonpolar molecule because it consists of two iodine atoms that are identical, with the same electronegativity. Nonpolar substances generally dissolve best in nonpolar solvents.
HCl (hydrochloric acid) is a polar solvent, so it is less likely to dissolve nonpolar iodine effectively.
H2O (water) is a polar molecule, but it does have some ability to dissolve nonpolar substances like iodine. However, water would not be the most effective solvent for iodine.
CH3OH (methanol) is a polar solvent, but it can dissolve nonpolar substances like iodine to some extent. While it may not be the best solvent, it could still dissolve iodine to a reasonable degree.
NH3 (ammonia) is a polar molecule and can dissolve iodine due to its ability to form hydrogen bonds. However, ammonia is less commonly used as a solvent for iodine compared to other solvents.
CS2 (carbon disulfide) is a nonpolar solvent, making it a good option for dissolving nonpolar iodine. Carbon disulfide is commonly used for this purpose.
Considering the above information, the best choice of solvent for iodine (I2) among the options provided would be CS2 (carbon disulfide).
