Final answer:
Chlorine gas (Cl2) is slightly soluble in water (H2O) due to dipole-dipole interactions and hydrogen bonding between the molecules.
Step-by-step explanation:
When considering the solubility of Cl2 (chlorine gas) in H2O (water), the intermolecular forces between the two substances play a role. Chlorine gas is slightly soluble in water due to the presence of dipole-dipole interactions and hydrogen bonding between the chlorine molecules and water molecules. These intermolecular forces allow for some dissolution of the Cl2 molecules in water, although the solubility is relatively low.
