Whih of the following liquids would make a good solvent for iodine?
HCl
H2O
CH3OH
NH3
CS2
How do you determine what will make a good solvent for something
You look at the solvent and see if it is polar. Same for solute. Remember the rule that like dissolves like. I2 is mostly non-polar (it is instantaneous dipole/induced dipole) so HCl and H2O would not be good solvents. CS2 is a linear molecule and non-polar. Both NH3 and CH3OH are polar but much less so than HCl and H2O. I would think I2 is most soluble in carbon disulfide. Check my thinking.

obviously bro
Ethanol (an alcohol) is a good solvent for iodine
Ethanol + iodine = iodine tincture
The best answer there is methanol CH3OH
Why did the chemistry book bring a clown to the party? Because it wanted to add a little "solvent-ertainment"!
Now, let's dive into your question. When determining a good solvent for a substance like iodine, we need to consider a few factors. First, we want a solvent that can dissolve iodine effectively. Second, we want a solvent that can form stable interactions with iodine molecules.
Out of the options you provided, HCl (hydrochloric acid) and NH3 (ammonia) can technically dissolve iodine. However, they tend to form chemical reactions with iodine rather than just acting as solvents. So, they might not be the best choice here.
H2O (water) is an excellent and commonly used solvent for iodine. It can form hydrogen bonds with iodine, helping it dissolve nicely. So, H2O is a great choice for your iodine-solvent needs!
As for CH3OH (methanol) and CS2 (carbon disulfide), they can also dissolve iodine quite well, but they have their own set of characteristics and applications that may or may not make them suitable for your specific purposes.
Remember, like in life, choosing the right solvent can be a "solvent-uous" decision. It depends on what you're trying to accomplish and what properties you're looking for. Happy experimenting!
To determine what will make a good solvent for a particular substance, you need to consider the intermolecular forces involved. These forces determine how well a solvent can dissolve a solute. Generally, "like dissolves like," which means that polar solutes dissolve in polar solvents, while nonpolar solutes dissolve in nonpolar solvents.
Iodine is a nonpolar solute because it consists of nonpolar covalent bonds. So, it will dissolve well in nonpolar solvents. Let's examine the options to see which one is nonpolar:
1. HCl: Hydrochloric acid is a polar solvent and may not be a good choice for dissolving iodine.
2. H2O: Water is a polar solvent, and since iodine is nonpolar, it would not dissolve well in water.
3. CH3OH (methanol): Methanol is a polar solvent and may not be ideal for dissolving iodine.
4. NH3 (ammonia): Ammonia is a polar solvent and may not dissolve iodine effectively.
5. CS2 (carbon disulfide): Carbon disulfide is a nonpolar solvent and would make a good choice for dissolving iodine because both substances are nonpolar.
Therefore, CS2 would be the best solvent for iodine among the given options.
