ANALYTICAL CHEMISTRY – MRII GRADED A+



Analytical Chemistry - correct answer branch of chemistry that deals with
the separation, identification, and composition of matter.


Qualitative Analysis - correct answer type of analysis that reveals the
component of the sample.


Quantitative Analysis - correct answer type of analysis that determines the
amount of components present in a sample.


Gravimetric method - correct answer deals with the measurement of the
mass of a substance that is chemically related to the analyte.


Volumetric Method - correct answer measures the volume of solution
necessary to react completely with the analyte.

,ANALYTICAL CHEMISTRY


Spectroscopic Method - correct answer measures the electromagnetic
radiation produced by the analyte or its interactions with it.


Electroanalytic Methods - correct answer measures the electrical
properties of the analyte such as current, potential, resistance, and amt.
of charge.


Analyte - correct answer a substance whose chemical constituents are
being identified and measured. ; unknown solution


Titrant - correct answer a substance that is added in titration; known
solution


Standard Solution - correct answer a solution of known concentration.


Standardization - correct answer process of determining the concentration
of an unknown solution.


Primary Standard - correct answer a substance of high purity used for
standardization.


Monoprotic Acid - correct answer substance that donates an H+ ion into
solution

, ANALYTICAL CHEMISTRY


Polyprotic Acid - correct answer substance that donates more H+ ion into
solution


Titration - correct answer determines the concentration of an identified
analyte


Direct Titration - correct answer the analyte reacts with the standard
solution directly.


Back Titration - correct answer an excess standard solution is added and
the excess is determined by the addition of another standard solution.


Replacement Titration - correct answer the analyte is converted to a
product chemically related to it and the product of such reaction is
titrated with a standard solution.


Ionization Reaction - correct answer reaction involving formation of ions.


Strong Acid/Base - correct answer completely ionized in solution.


Weak Acid/Base - correct answer partially ionized in solution.


Acidic salt - correct answer is formed from the reaction of a strong acid and
weak base.
