The experimental results of positron annihilation and sound velocity experiments in aqueous solutions of formamide and ethyl alcohol are compared. The concentration dependences of annihilation parameters and of adiabatic compressibility differ significantly for these systems, indicating hydrophobic hydration occuring in the case of water-alcohol system and hydrophilic one in the case of water-formamide.
