What is the function of 1/10-phenanthroline?

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.

What 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.

Is 1,10-phenanthroline monodentate or bidentate?

bidentate ligand
… 1,10-phenanthroline (phen), which is a bidentate ligand that acts as chelating agent, is an important starting compound in coordination chemistry for organic, inorganic and supramolecular synthesis [22] .

What observable color or opacity change occurs when 1/10-phenanthroline is added?

Some chemical indicators have very narrow and sensitive range. For instance, one example of a sensitive oxidation-reduction indicator is ferrous 1,10-phenanthroline. The colour of the indicator changes from red to pale blue if the oxidation potential is increased to 1.08 volts from 1.04 volts.

What is phenanthroline method?

A rapid, accurate method for the determination of iron using hydroxylamine hydrochloride, sodium acetate buffer, and 1,10-phenanthroline is described. The ash is taken up with hydrochloric acid (1 + 1) and heated for 5 minutes. No interference from pyrophosphates, copper and nickel was observed.

What does phen mean in chemistry?
