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

Based on Ashley's observations what statement can she make about the solubility of the three matensis?

- Sand is more soluble than sat and Tour

- Flour is more soluble than salt and sand

- Sand is the least souble when compared to four and salt

- Sat is the least soluble when compared to four and sand
