Titration | method used to determine the concentration of a substance in a solution
🗑
|
||||
Dissociation | The separation of ions that occur when an ionic compound dissolves
🗑
|
||||
Electrolyte | A substance that dissolves in water to give the solution the ability to conduct electricity.
🗑
|
||||
Base | proton acceptors identified by release of hydroxide ions.
🗑
|
||||
H3O+ | Hydronium
🗑
|
||||
Molarity | Number of moles of solute in one liter of solution
🗑
|
||||
Molality | The concentration of a solution expressed in moles of solute per kilogram of solvent
🗑
|
||||
Colligative Properties | Depend on the concentration of solute particles but not on their identity.
🗑
|
||||
Acid | proton donors that yield hydronium ions in water solution
🗑
|
||||
Concentration | The amount of solute in a given amount of solvent in a solution.
🗑
|
||||
Boiling Point Elevation | The difference between the boiling points of the pure solvent and a non electrolyte solution of that solvent and is directly proportional to the molal concentration of the solution.
🗑
|
||||
Freezing Point Depression | The difference between the freezing points of the pure solvent and a solution of a non electrolyte in that solvent, and is directly proportional to the molal concentration of the solution.

🗑
|
||||
Solubility | The capability to dissolve.
🗑
|
||||
End point | The point in a titration at which no more titrant should be added. It is determined, for example, by a color change in an indicator or by the appearance of a precipitate.
🗑
|
||||
Neutralization | a chemical reaction in which an acid and a base react to form a salt.
🗑
|
||||
pOH | hydroxide ion concentration
🗑

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.
