Solubility Test

Key terms & info for solubility & change of state

The ability for one substance (solute) to dissolve into another (solvent) Solubility
The substance in a solution that is being dissolved, there is less of this substance than the other Solute
The substance in a solution that dissolves another substance; there is more of this substance than the other Solvent
A mixture of at least one solute and one solvent, where the solute is completely dissolved and mixed equally throughout Solution
A solution that already has so much dissolved solute, that no more will dissolve Saturated Solution
A solution that will continue to dissolve more solute if it is added Unsaturated Solution
A mixture containing large undissolved particles, that can be filtered or will settle out Suspension
A mixture containing small undissolved particles, too small to see, that will not settle Colloid
The change of state from a solid to a liquid Melting
The change of state from a liquid to a solid Freezing
The change of state from a liquid to a gas Evaporation
The change of state from a gas to a liquid Condensation
The change of state from a solid directly to a gas Sublimation
What are the factors that affect solubility? Mixing, Temperature, Particle Size & Already Dissolved Solute
In a solution of Gatorade mix and water, identify the solvent and the solute Solvent-Water, Solute-Mix
What happens to the particles in matter as the temperature is increased? The particles move faster, and begin to expand
If the temperature of a substance decreases, how does it affect the volume? The volume will decrease
What happens to the density of a substance as it is heated? The volume increases, to the density goes down
How does temperature affect solubility? Substances dissolve easier as the temperature increases
If sugar won’t dissolve into my iced tea, how can we increase the solubility? Add more tea (solvent) or increase the temperature
What process causes the driveway to dry off after it rains? Evaporation
