Will HCI (C) or NaCl (s) be more soluble in the solvent CH,OCH,? Why? Check all that apply. HCI (g) will be more soluble in CH OCH The lon-dipole forces in an NaCICH,OCH, solution are more likely to overcome solute-solute Interactions (ie. Ionic bonding) than the dipole-dipole forces in an HCI/CH,OCH, solution (.e. dipole-dipole between HCl molecules). The dipole-dipole forces in an HCVCH,OCH, solution are similar in strength to the dipole-dipole forces between CH,OCH, molecules HCI is capable of hydrogen...
