|
Aqueous Solution
|
solutions with water as the solvent
|
|
|
Complete Ionic Equation
|
the equation that shows separately all species, both ions and molecules, as they are persent in solution
|
|
|
Net ionic equation
|
the equation that shows only those species int he reaction that undergo change
|
|
|
Overall equation
|
the equation that shows all of the reactants and products in undissociated form
|
|
|
Precipitation Reaction
|
the formation of an insoluble product or products from reactants in solution
|
|
|
Solubility
|
the concentration of solute that exists in equilibrium with an excess of that substance
|
|
|
Solute
|
any substance being dissolved to form a solution. Solutes are usually present in lesser quantity than the solvent.
|
|
|
Solvent
|
the substance that has the same physical state as the solution. It is generally the compenent present in largest quantity; in aqueous solutions, the solvent is water
|
|
|
Spectator Ions
|
ions present in solution that do not undergo change
|
|
|
Strong Electrolytes
|
substances that dissociate or ionize completely in solution.
|
|
|
Weak Electrolytes
|
substances that only partially dissociate or ionize in solution
|
|
|
Concentration
|
the amount of solute in a given quantity of that solution
|
|
|
Molarity
|
the concentration unit defined as the number of moles of solute in one liter of solution
|
|
|
Pipet
|
a device calibrated either to deliver or to contain a specific volume of liquid; it is used to measure accurately a fixed volume of solution.
|
|
|
Volumetric Flask
|
a container calibrated to hold an accurately known volume of liquid
|
|
|
End point
|
the point in a titration at which the indicator changes color
|
|
|
Equivalence point
|
the point in a titration at which the reactants are present in stoichiometrically equivalent amounts
|
|
|
Gravimetric Analysis
|
the selective precipitation of one component of a solution followed by isolation and weighing of the precipitate to determine the amount of that component
|
|
|
Indicator
|
a compound that changes color at the endpoint of titration. The indicator should be chosen so that the endpoint coincides as nearly as possible with the equivalence point
|
|
|
Standard Solution
|
a solution of accurately known concentration
|
|
|
Titration
|
a procedure for the determination of the quantity of one substance by the addition of a measured amount of a second substance.
|
|
|
Volumetric Analysis
|
a quantitative determination in which the volume of a solution of substance is measured.
