Solubility Quiz Card
| Question/Term | Answer/Definition |
|---|---|
| soluble | a substance that can be dissolved in another |
| What is an example of soluble? | sugar in tea |
| Insoluble | a substance that cannot be dissolved in another |
| What is an example of insoluble? | marble or rock in water |
| Dissolve | to break up into particles too small to see with the naked eye |
| What are different ways to dissolve solids, liquids, and gases? | solid to liquid-> increase temp.(ice), stir (ice tea mix), grind up gas to liquid->cool, increase pressure |
| Solvent | the part of a solution that is present in the largest amount and dissolves a solute |
| What is an example of a solvent? | water (that you dissolve the sugar IN) |
| Solute | the part of a solution present in a lesser amount and dissolved by the solvent |
| What is an example of a solute? | sugar ( the thing that gets dissolved) |
| Solution | a well-mixed mixture containing a solvent and at least one solute that has the same properties throughout. |
| What is an example of a solution? | Air, Soft drinks, Glass cleaner, Gasoline |
| Solubility | a measure of how much solute can dissolve in a given solvent at a given temperature |
| Concentrated solution | a mixture that has a lot of solute dissolved in it. |
| What is an example of a concentrated solution? | tea that is really dark and full of flavor |
| Dilute solution | a mixture that only has a little solute dissolved in it |
| What is an example of a dilute solution? | tea that is really light and watery, not very flavorful |
| Saturated solution | a mixture that contains as much dissolved solute as is possible at a given temperature. |
| What is an example of a saturated solution? | salt in water where some salt dissolves but than the water becomes saturated and no more salt will dissolve |
| Unsaturated solution | a mixture that contains less dissolved solute than is possible at a given temperature |
| What is an example of a unsaturated solution? | salt in water where there can be more salt added and it would still dissolve |
| Precipitate | A solid that falls out of a solution as it is cooled. |
| Mixture | two or more substances that are mixed together but not chemically combined |
| What is an example of a mixture? | dirt (dirt, sand, plant parts) |
| Homogeneous mixture | a mixture in which substance are evenly distributed throughout |
| What is an example of a homogeneous mixture? | salt water, steel, air (won't settle at the bottom of the container) |
| Heterogeneous mixture | a mixture in which pure substance are unevenly distributed throughout the mixture |
| What is an example of a heterogeneous mixture? | fruit salad, trail mix, pizza (things that can be separated |
| Colloid | a mixture containing small, undissolved particles that do not settle out |
| What is an example of a colloid? | jello, fog, milk |
| Suspension | a mixture in which particles con be seen and easily separated by settling or filtration |
| What is an example of a suspension? | Italian dressing, snow globe, pulp in orange juice |
| When a solution is saturated the amount that is dissolved in 100cm cubed of a solvent is called ______ of the solution. | solubility |
| The solubility of salt in water is approximately 36g/100cm cubed. That is ____g is the largest amount of salt you can dissolve in 100cm cubed of water. | 36 |
| When a solution of a solid dissolved in a liquid is heated, the solubility of the solution ________. That is, more solid will dissolve. | increases |
| After a solution is heated, and then is allowed to cool, the solubility will __________. That is less solid will dissolve. | decrease |
| If the solution is already saturated when it is cooled, the solid that can no longer stay dissolved will reappear as _______ called precipitate. | crystals |
| If the solubility of a solution is measured at different temperatures and then plotted on a graph, you will get a _________ for that solution. This can be used to determine the solubility of the solution at any temperature. | solubility curve |
| Gases can also be ______ in a solution. | solutes |
| If a solution containing gas dissolved in a liquid is heated, the solubility will ________. That is, less gas will dissolve. | go down |
| If a solution containing gas is cooled, the solubility will _______. That is, more gas will dissolve. | go up |
| The _______ effect that occurs in a solution with solids and gases. | opposite |
