Question

At equilibrium in a solution:

a) Solute particles that are not in solution remain suspended
b) Solvent particles leave the solution and form crystals
c) Solute moves from the solid state into the solution and back to a solid
d) Heat is transferred from the solvent to the solute

Answer 1

At equilibrium in a solution, each particle of the solute is surrounded by particles of the solvent, carrying the solute from its original phase. Solute that is added to a saturated solution will dissolve and recrystallize at the same rate, resulting in no net dissolution. Solution equilibrium is the physical state described by the opposing processes of dissolution and recrystallization occurring at the same rate.

Step-by-step explanation:

At equilibrium in a solution: Each particle of the solute is surrounded by particles of the solvent, carrying the solute from its original phase. When a solute is added to a saturated solution, it dissolves and recrystallizes at the same rate, resulting in no net dissolution. Solution equilibrium is the physical state described by the opposing processes of dissolution and recrystallization occurring at the same rate.
