A __________ __________ is any highly stable substance whose purity is extremely high from which we can determine the concentration of another solution. It will ideally have a high __________ __________.
1) Primary standard 2) Molecular weight
The NaOH base used is an example of a __________ __________ because we are using the concentration of the base as determined from the primary standard to find the concentration of the acid.
1) Secondary standard
A __________ is the use of a buret to quantitatively deliver a known amount of a solution of known concentration as it reacts with a known amount of solution of unknown concentration.
The reach between two solutions is known as the __________ __________ or __________ __________. At this point the two reactants are chemically equivalent.
1) Stiochiometric point 2) Equivalent point
The solution whose concentration is known is called a __________ while a solution whose concentration is being analyzed is called the __________.
1) Tirant 2) Analyte
An __________ is usually an organic dye that changes color when the reaction is complete. This color change indicates to the observer that the reaction is complete and is called the __________ __________.
