Solutions and Solubility

Ashley wants to compare the solubility of three materials: salt, sand, and flour. She fills three beakers with 500 mL of water each. She then adds the same amount of each solute to the beaker. The picture shows the particles left after mixing.

Based on Ashley’s observations, what statement can she make about the solubility of the three materials?

• Sand is more soluble than salt and flour.

• . Flour is more soluble than salt and sand.

• Sand is the least soluble when compared to flour and salt.

• Salt is the least soluble when compared to flour and sand.
