Complexometric Titration, Precipitation Titration, and Gravimetry
Complexometric titration involves the formation of a complex by reacting a metal ion with one or more ligands. A visual indicator often detects the…
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by…
Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or…
Each EDTA molecule has six binding sites: four carboxyl groups and two amino groups. The fully protonated form of EDTA is represented as H6Y2+.…
The EDTA titration types for metal ion analysis include direct titration, back-titration, and replacement titration.
Direct titration involves…
Unlike direct titration, back-titration, and displacement titration, indirect titration is an EDTA titration method for quantifying anions. In the…
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the…
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These…
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of…
In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a…
In gravimetry, the precipitant is chosen carefully to obtain a pure solid that can be easily filtered. Common inorganic precipitants can be used to…
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An…
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate.…
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large…
While multiple advances in mass spectrometry (MS) instruments have improved qualitative and quantitative proteome analysis, more reliable front-end…
Determination of Carbonyl Functional Groups in Bio-oils by Potentiometric Titration: The Faix Method
Carbonyl compounds present in bio-oils are known to be responsible for bio-oil property changes upon storage and during upgrading. Specifically,…
