1) between calcium cations (Ca²⁺) and chloride anions (Cl⁻) and water, there is ion-dipole attractions. An ion-dipole force is an attractive force that results from the electrostatic attraction between an ion (Ca²⁺ and Cl⁻) and a neutral molecule that has a dipole (H₂O).
2) between ethanol (CH₃CH₂OH) and water, there is hydrogen bonding, because both molecules have oxygen and hydrogen.
