AdministratorWhat type of ligand is 1/10 phenanthroline?
chelating bidentate ligand
1,10-Phenanthroline (phen) is a classic chelating bidentate ligand for transition metal ions that has played an important role in the development of coordination chemistry [1], [2], [3] and still continues to be of considerable interest as versatile starting material for organic, inorganic and supramolecular chemistry.
What is the function of 1/10 phenanthroline?
1,10-Phenanthroline forms a stable complex with Fe(II) ion called ferroin, which is used as an indicator in Fe(II) salt titrations. Ferroin is also used in the determination of other metals, such as nickel, ruthenium, and silver.
Which ion is detected by 1,10-phenanthroline?
1,10-Phenanthroline forms with Fe(III) a blue complex (λmax 585 nm) which has been used for determining larger amounts of iron.
What is the density of 1/10-phenanthroline?
1.31 g/cm³1,10-Phenanthroline / Density
What is the purpose of adding hydroxylamine hydrochloride to each sample?
The hydroxylamine hydrochloride is added to the solution to lower the pH and act as a reducing agent to prevent the oxidation of Fe(II) to Fe(III) [4]. The sodium acetate is added to the solution to act as a pH buffer to maintain the pH in a range where all of the aqueous iron will reside in the Fe2+ oxidation state.
Which Coloured complex is formed when iron react with 1/10-phenanthroline?
red/orange ferroin complex
We will determine the Fe content using a popularly used phenanthroline method. In this method the red/orange ferroin complex formed by the reaction of Fe(II) with 1,10-phenanthroline is detected (Fig. 14.1).
Why ferroin is used as indicator in the COD test?
The excess potassium dichromate is titrated with ferrous ammonium sulphate (FAS) until all of the excess oxidizing agent has been reduced to Cr3+. The oxidation-reduction indicator ferroin is also added during this titration as it changes its color from red to pale blue when oxidized.
What is the chemical formula for phenanthroline?

What is the solubility of 1 10 phenanthroline in methanol?
1,10-Phenanthroline is soluble in methanol at 500 micrograms per mL, or in water at 3 milligrams per mL. It is also soluble in benzene and acetone. My question is not addressed here, how can I contact Technical Service for assistance?
What is EC1 10 phenanthroline?
