|---|---|---|---|---|---|
| Solutions are what kind of mixture? | homogenous
🗑
|
||||
| What states can solution be in? | gas, liquid, or solid
🗑
|
||||
| solvent | he component in the solution with the highest concentration
🗑
|
||||
| condensed states | the liquid states, and the solid states
🗑
|
||||
| What if the attractive force of solute molecules for other solute molecules are greater than the attractive forces of solute molecules for water? | then the solute will not dissolve
🗑
|
||||
| What does the lattice energy describe? | the attractive force between the solute molecules (like ions)
🗑
|
||||
| solvation | process where the solute-solvent interactions are strong enough to separate, surround, and disperse a solute
🗑
|
||||
| hydration | the solvation process where the solvent is water
🗑
|
||||
| enthalpy of solvation | the process of solvation that involves energy changes. This is a physical process, not chemical
🗑
|
||||
| enthalpy of solvation 1: | dispersing the solutes. It is the lattice energy
🗑
|
||||
| energy of solvation 2: | water molecules have to separate from one another to provide the necessary space to accomodate the dispersed solutes
🗑
|
||||
| energy of solvation 3: | energy associated with the formation of solvent-solute intearction
🗑
|
||||
| separating the solute molecules from each other is endothermic or exothermic? | endothermic
🗑
|
||||
| disrupting solvent-solvent interaction to allow space for dispersed solute molecules is endothermic or exothermic? | endothermic
🗑
|
||||
| formation of solvent-solute inteaction is endothermic or exothermic? | exothermic
🗑
|
||||
| Process in which the overall heat energy of the system decreases tend to be what? | spontaneous (example: a negative value for the overall heat change indicates spontaneity)
🗑
|
||||
| processes in which the disorder of the system increases tend to be what? | spontaneous
🗑
|
||||
| entropy | the degree of disorder
🗑
|
||||
| high entropy is what? | disordered
🗑
|
||||
| low entropy is what? | ordered
🗑
|
||||
| concentrated solution | solute is present in high concentration
🗑
|
||||
| diluted solution | where the solute is present in low concentration
🗑
|
||||
| ppm stands for? | parts per million
🗑
|
||||
| ppb stands for? | parts per billion
🗑
|
||||
| the density of diluted aqueous soltuion can be assumed to be equal to the density of what? | pure water
🗑
|
||||
| 1.0 L of diluted aqueous solution has a mass of what? | 1000 g
🗑
|
||||
| the sum of mole fractions of all components in a solution (including the solution itself) must equal | 1.0
🗑
|
||||
| molality (m) | moles of solute / kilograms of solvent component
🗑
|
||||
| crystallization | collision of dispersed ions with remaining crystals, resulting in an increase in the crystal mass
🗑
|
||||
| saturated | a solution that is in dynamic equilibrium with undissolved solute
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
