Hydrogen Chloride, HCl, Is a Gas at Room Temperature

question 100

Multiple Choice

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.
