|---|---|---|---|---|---|
| colligative properties | show 🗑
|
||||
| solubility | show 🗑
|
||||
| show | Moles of solute per kilogram of solvent
🗑
|
||||
| mole fraction | show 🗑
|
||||
| show | ... where the intermolecular forces being broken in the solute are being replaced by equal or stronger forces between the solvent and the solute.
🗑
|
||||
| show | ... it is independent of temperature and pressure.
🗑
|
||||
| show | Ionic substances that dissociate completely
🗑
|
||||
| show | Ionic compounds that do not dissociate completely
🗑
|
||||
| show | ...conduct electricity better than weak electrolytes.
🗑
|
||||
| show | ("i") The number of ions a unit of a substance will produce in a given solution. (Ex: For NaCl, i = 2)
🗑
|
||||
| ionizability | show 🗑
|
||||
| show | ... are strong electrolytes, whether soluble or not.
🗑
|
||||
| show | All Group I (Li, Na, K, Rb, Cs) and ammonium salts are soluble.
🗑
|
||||
| Solubility of salts in water (2) | show 🗑
|
||||
| show | All silver, lead, and mercury salts are insoluble (except for compounds soluble under rule 2).
🗑
|
||||
| Phase solubility (1) | show 🗑
|
||||
| show | The solubility of gases in liquids tends to decrease with increasing temperature.
🗑
|
||||
| Phase solubility (3) | show 🗑
|
||||
| show | are only dependent on the number of particles in the solution, and are independent of the identity of particle.
🗑
|
||||
| vapor pressure | show 🗑
|
||||
| show | Having high vapor pressure.
🗑
|
||||
| boiling point | show 🗑
|
||||
| show | ... has a lower vapor pressure and boils at a higher temperature than pure water.
🗑
|
||||
| show | The partial vapor pressure of a particular substituent in a solution is proportional to its mole fraction.
🗑
|
||||
| show | The total vapor pressure over a solution is the sum of the partial vapor pressures of the substituent liquids.
🗑
|
||||
| vapor-pressure depression | show 🗑
|
||||
| show | A solution where all intermolecular forces are equal.
🗑
|
||||
| show | ... dissolution of a solute in a solvent closes the entropy gap between the soution and vapor phases. The smaller increase in entropy from evaporation leads to less tendency to evaporate. Occurs only in solid-liquid solutions.
🗑
|
||||
| show | ... when vapor pressure is depressed, higher temperature is needed to vaporize the solution. Occurs in only solid-liquid solutions.
🗑
|
||||
| The behavior of a liquid-liquid solution deviates from Raoult's Law when... | show 🗑
|
||||
| show | = (k)(i)(m); k = solvent's boiling point elevation constant, i = solute's van't Hoff factor, m = molality of the solution
🗑

||||
| Freezing-point depression occurs because... | show 🗑
|
||||
| freezing-point depression | show 🗑
|
||||

|
||||
| show | F = -kx
🗑
|
||||
| elastic potential energy | show 🗑
|
||||

|
||||
| frequency of an oscillating pendulum | show 🗑
|
||||
| wave speed | show 🗑
|
||||
| show | = sqrt(T/D); T = tension, D = linear density
🗑
|
||||
| show | ... the type of wave and the characteristics of the medium, and not the frequency. Light through a material medium is the only exception.
🗑
|
||||
| When a wave passes into a different medium... | show 🗑
|
||||
| show | ... energy, not frequency, wavelength, or wave speed.
🗑
|
||||
| fundamental | show 🗑
