Identify the primary solute - solvent attractions when i) cacl2 and ii) ethanol, ch3ch2oh each dissolve in water.

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 (Ca ²⁺ and Cl⁻) and a neutral molecule that has a dipole (H ₂O).

2) between ethanol (CH₃CH₂OH) and water, there is hydrogen bonding, because both molecules have oxygen and hydrogen.
