Question

Taylor pours a sample of a pink liquid onto a plate. A few days later, Taylor observes only red, white, and black solid particles on the plate. What is the best explanation for this result

Answer 1

The best explanation is that the pink liquid contained dissolved metal salts that, upon evaporation of the liquid, left behind red, white, and black solids due to crystallization.

Step-by-step explanation:

The student observed that a pink liquid turned into red, white, and black solid particles after being left on a plate for a few days. This could be an example of evaporation followed by crystallization. The liquid likely contained dissolved metal salts, which upon evaporation of the solvent, left behind colored solids. These colors correspond to different metal salts, which are identifiable by characteristic colors. For instance, red may indicate the presence of strontium or lithium salts, white could suggest the presence of silver salts and black might be indicative of manganese or copper oxide. This process is similar to the formation of a precipitate when two clear liquids are mixed and is consistent with the given examples of color changes and precipitate formation in various chemical tests.
