Asolute 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

Option (B) is the correct answer.

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.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
