Students were investigating two clear solutions. Students added 2 mL of one solution to a beaker of the other solution. The result is pictured below.
A student observed that the temperature of the beaker did not have any noticeable changes, however the mass of the substances in the beaker increased. A red precipitate formed where the substance was poured into the beaker. The precipitate separated from the solution and fell to the bottom of the beaker. Which observation provides the best evidence that a chemical change formed a new substance in the beaker?
A. A precipitate is formed.
B. The precipitate fell to the bottom.
C. The temperature did not change.
D. There is an increase in mass.
What is B.?
