You 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 swollen and has taken in water. What can you conclude? A. The concentration of ions in the unknown solution is more than 100 ppm.
B. The concentration of ions in the unknown solution is less than 100 ppm.
C. The solutions have the same concentrations.
D. Not enough information to determine.
