Question

A solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solution must be

A)dilute  

B) saturated   C) unsaturated   D)  supersaturated

Answer 1

when the solute can no longer dissolve in the solution the solvent becomes SATURATED. When no more solute can dissolve and if you look at the bottom of the beaker, test tube, pan, or glass of cold tea you can see the solute permeating out as little particles .

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

A solution that has maximum concentration of solute particles and on adding more solute the particles of solute remains undissolved is known as a saturated solution.

Whereas when particles of solute keep on dissolving in a solution then it is known as an unsaturated solution.

Thus, we can conclude that a solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solution must be saturated.
