Question

Choose a statement below that is TRUE.

A) A solution will form between two substances if the solute-solute interactions are strong enough to overcome the solvent-solvent interactions.
B) A solution will form between two substances if the solute-solvent interactions are small enough to be overcome by the solute-solute and solvent-solvent interactions.
C) A solution will form between two substances only if the solvent-solvent interactions are weak enough to overcome the solute-solvent interactions.
D) A solution will form between two substances if the solute-solvent interactions are of comparable strength to the solute-solute and solvent-solvent interactions.

Answer 1

Answer:

D) A solution will form between two substances if the solute-solvent interactions are of comparable strength to the solute-solute and solvent-solvent interactions.

Explanation:

Solvent-solute interactions determine formation of the solution.  A solution is formed when the solvent- solvent interactions and the solute-solute interactions are less than or equal to the solvent-solute interactions.

For example,  if NaCl is dissolved in water, the crystal lattice of the salt must break to dissolve in water and thus formation of solution takes place.
