Question

Fill in the blanks with its definition or description.

a. _________ The point in a titration when the added amount of standard reagent is equal to the amount of analyte being titrated.
b. _________The analyte is titrated with the standard reagent and the volume of standard solution required to complete the reaction is measured.
c. _________A reagent that is pure and stable, which can be used directly after weighing.
d. _________The analyte that is being analyzed in the titration.
e. _________Standard reagent is added in excess to ensure complete reaction with the analyte.
f. _________The excess reagent is then titrated with a second standard reagent.
g. _________A solution, whose concentration is known, often made from a reagent of known purity.
h. _________The standard reagent of known concentration that is added from a buret to the analyte solution.
i. _________The analyte does not react directly with the titrant so it is converted to another form which will react with the titrant.
j. _________The point in a titration when a change in the analyte solution is observed, indicating equivalency.
k. _________It is added to the analyte solution and aids in the observation of the completion of the reaction.

Answer 1

a) equivalence point

b) direct titration

c) primary standard

d) titrand

e) Back titration

f) back titration

g) standard solution

h) standard solution

I) indirect titration

j) end point

Step-by-step explanation:

A volumetric analysis is one in which a solution of unknown concentration is determined from its volume. This is commonly referred to as titration.

In titration, a standard solution is reacted with another solution of unknown concentration. The point at which the concentration of the standard solution is equal to that of the analyte is known as the equivalence point (usually indicated by a colour change). An indicator may be added to the analyte solution to help identify when the reaction is complete.
