Describe what happened in a test tube where big red crystals were mixed with water and the result was a red, transparent liquid with a few red grains on

the bottom.

Describe what happened in a test tube where big red crystals were mixed with water and the result was a red, transparent liquid with a few red grains on

the bottom.

The red crystals DISSOLVED in the water (it was a solute, the

water was a solvent). The solution became saturated so

the last red grains didn’t dissolve. The crystals are more

dense than water!
