Dissolving Process

cava s2d19 303 2.02 Dissolving Process

QuestionAnswer
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**.
