When a solution is saturated and additional solute sits at the bottom of the vessel: Select the correct answer below: Some solute will precipitate but no more will dissolve, so the concentration will fall. More solute will dissolve, but no more will precipitate, so the concentration will rise. The solute will continue to dissolve and precipitate at precisely the same rate so that the concentration will remain fixed. There is no activity involving the solute and solvent, so the concentration will remain fixed.
