Matti is given two bottles of copper (II) sulfate solutions in her senior high chemistry lab. She is told that one bottle contains a saturated solution and the other one contains an unsaturated solution. The solutions are the exact same color and have no particles in the bottles. Describe what Matti can do to distinguish between the two solutions. A- 米 U X2 x? #3 X Next page age You are logged in as Kaylee Krys (Log out) VLL Chemistry CP 2021-2022 (Fickett).
