Question

Arrange the following compounds in order of increasing solubility in water: O2, LiCl, Br2, methanol (CH3OH).

Answer 1

Answer:

Methanol is more soluble > LiCl > Br2(l) > O2(g)

Explanation:

Arrange the following compounds in order to increase water solubility:

O2 = nonpolar gas, MW(Molecular weight)= 32 g/mol

LiCl= ionic salt, dissociate in Li+ and Cl-ions Br2= nonpolar liquid;

MW= 319.4 g / molmethanol(CH3OH)= polar liquid, MW= 32 g/mol

Therefore, with this data: polar methanol comes then, remember that like dissolves like, so polar + polar will dissolve pretty good LiCl appetite. However keep in mind that it will have a "saturation" point, since then most salts will not be infinitely soluble, Br2(l); since it is a non-polar liquid, it will have low solubility, but since it is a halogen, it will have low solubility.

Methanol is more soluble > LiCl > Br2(l) > O2(g)
