Solubility Test
Key terms & info for solubility & change of state
| Question | Answer |
|---|---|
| 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 |
