Sign in to playDrag a shaker to sprinkle in solid solute or a dropper to add concentrated solution to a beaker of water, hold the tap to add water or drain some away, and drag the evaporation slider to concentrate the solution gradually. Drop the concentration probe into the solution to read the concentration directly in mol/L; once the solubility limit is exceeded, the excess settles at the bottom of the beaker as a solid and no more will dissolve. Eight familiar solutes (sugar, table salt, copper(II) sulfate, potassium permanganate, potassium dichromate, potassium chromate, cobalt(II) chloride, nickel(II) chloride) each have their own color and solubility limit.
