Hydrogen chloride, HCl, is a gas at room temperature. Would you expect this material to be very soluble or not very soluble in water?
A) HCl is very soluble in water by virtue of the dipole/dipole attractions occurring between the HCl and H2O molecules.
B) It is not very soluble because it is a gas, and all gases have very low solubility in water at room temperature.
C) HCl is very soluble in water because it is such a small molecule, there is little electrical attraction to other HCl molecules.
D) It is not very soluble because as a gas with low density, it floats to the surface of the water and then into the surrounding atmosphere.
