Sign in to playDrag the two sliders for amount of solute (moles) and volume of solution to see the molar concentration C_M = n/V change instantly, shown by the color of the solution in the beaker. Switch solutes (table salt, copper(II) sulfate, potassium permanganate, potassium dichromate) to see that each one has its own saturation limit: beyond it the excess settles as crystals at the bottom of the beaker and the concentration stops rising. Based on the "Molarity" simulation by PhET Interactive Simulations, University of Colorado Boulder (CC BY 4.0); rewritten.
