Titration Flashcards
Acidic or basic titrant reacts with an analyte that is a base or an acid
Acid Based Titration
Involving a metal–ligand complexation reaction
Complexometric Titration
- where the titrant is an oxidizing or reducing agent
Redox titration
The analyte and titrant react to form a precipitate
Precipitation titration
He is considered the pioneer and inventor of titrimetric analysis in early 19th century.
JJ. Gay Lussacs
He developed an alkaline method where an acid of known concentration was added until an indicator changes.
F. Descroizilles
______ establishment of the pH scale in 1909
provided a rigorous means for comparing visual indicators.
Sorenson’s
The determination of acid–base dissociation constants made the calculation of theoretical titration curves possible, as outlined by ________ in 1914.
Neils Bjerrum
The _______ , or _________
constant for a solvent relates the concentration of the protonated solvent to that of the deprotonated solvent.
dissociation, autoproteolysis
For _________, which can act as both proton donors and proton acceptors, the autoproteolysis reaction with an equilibrium constant.
amphoteric solvents
(also known as wet chemistry methods) use separations such as precipitation, extraction, and distillation and qualitative analysis by color, odor, or melting point.
Classical Method
Use an apparatus to measure physical
quantities of the analyte such as light absorption, fluorescence, or conductivity.
The separation of materials is accomplished using chromatography or electrophoresis methods
Instrumental Method
Titration curve in form of s shaped graph
Sigmoidal
An ion or molecule, which the central metal atom or ion to form a coordination complex
Ligand Complex
Another name for Piston burrette
Digital
Analytical sensors used to measure pH, or the negative logarithm of the hydrogen ion activity, in a solution.
pH electrode
Another name for complexometric titration, where a colored complex is used to determine the end point of titration.
Chelatometry
Kjedahl analysis an acid-based titrimetic method for determining the amount of _____ in organic compounds
Nitrogen
Analysis an acid-based titrimetic method for determining the amount of nitrogen in organic compounds
Kjedahl
A chemical used as an indicator for presence of oxidizers and used in medicine as a tester or evaluator of antibiotics.
Fe(SCN) 2+
A chemical used in 20th century as treatment of hypertension, it is toxic irritant and an environment al hazard.
Thiocyanate
An example of weak based commonly used in acid base titration
Ammonia
An example of strong acid used in acid based titration process.
Hydrogen Chloride
An indicator in strong acid titration
Phenolphthalein
It was first introduced as a strong based titrant in 1846
Sodium Hydroxide
Factors affecting titration
Absorbance of light
Temperature
Concentration of titrants
EDTA
Ethylenediaminetetraacetic Acid
