You conduct an experiment to determine the concentration of ions in an unknown solution. You place 300mL inside a dialysis bag and place the bag into a beaker of water with an ion concentration of 100 ppm (parts per million). When you check the experiment an hour later, the bag is deflated and has lost much of its water. What can you conclude?

You can confidently conclude that the concentration of the unknown solution is less than 100ppm. Because the concentration of the liquid in the beaker is higher than that of the unknown solution that is why water move out of the dialysis bag into the beaker of water. Thus, the solution inside the beaker is an hypertonic solution, that is why it deflated the dialysis bag.
