Solutlon 1 Solution 2 Compound A Compound B dissolved in dissolved in water at 25°C water at 25°C The student observed that the temperature changed from 25°C to 23°C when the solutions were combined and that a white substance rapidly formed and settled to the bottom of the container. What most likely happened to produce these results? F) One of the original compounds came out of solution. G) The solutions reacted chemically. H) Some of the water froze into ice crystals. 1) Rapid evaporation of water occurred, leaving a solid.
