Dissolving Process
cava s2d19 303 2.02 Dissolving Process
| Question | Answer |
|---|---|
| When a solute dissolves in a solvent, a [...] is formed. | When a solute dissolves in a solvent, a solution is formed. |
| A solid dissolves when particles of a solvent [...] with it and break off pieces. | A solid dissolves when particles of a solvent collide with it and break off pieces. |
| [...] area affects how fast a given amount of solid solute will dissolve. | Surface area affects how fast a given amount of solid solute will dissolve. |
| More surface area of a solid solute = more places for solvent molecules to [...] with it. | More surface area of a solid solute = more places for solvent molecules to collide with it. |
| Higher temperatures = [...] rate of collisions | Higher temperatures = higher rate of collisions |
| Higher temperatures = [-er] dissolving. | Higher temperatures = faster dissolving. |
| higher collision rate = [-er] dissolving. | higher collision rate = faster dissolving. |
| large chunks have less [...] area than the same amount broken up into small pieces. | large chunks have less surface area than the same amount broken up into small pieces. |
| Dissolution = the rate of [...] | Dissolution = the rate of dissolving |
| Rate is another word for [...]; how much happens **over time**. | Rate is another word for speed; how much happens **over time**. |
| You can't measure a rate without measuring **[...]**. | You can't measure a rate without measuring **time**. |
| [S-] is the **total amount** of solute that will dissolve under certain conditions. | Solubility is the **total amount** of solute that will dissolve under certain conditions. |
| Dissolution (rate) and Solubility [are / are not] the same thing. | Dissolution [rate] and Solubility are NOT the same thing. |
| Solutes that do not dissolve in a solvent are called *[...]* | Solutes that do not dissolve in a solvent are called *insoluble* |
| A [-ed] solution is one that has dissolved the maximum amount of solute possible. | A saturated solution is one that has dissolved the maximum amount of solute possible. |
| A [...] curve shows you the solubility of a solute under different conditions (usually different temperatures). | A solubility curve shows you the solubility of a solute under different conditions (usually different temperatures). |
| The solubility of a gas varies with [...]; but not liquids or solids. | The solubility of a gas varies with pressure; but not liquids or solids. |
| Higher pressures = higher [...] solubility | Higher pressures = higher gas solubility |
| Rate is another word for speed; how much happens **over [...]**. | Rate is another word for speed; how much happens **over time**. |
