Ferroin is suitable as a redox indicator, as the color change is reversible, very pronounced and rapid, and the ferroin solution is stable up to 60 °C. It is the main indicator used in cerimetry. [4] Nitroferroin, the complex of iron(II) with 5-nitro-1,10-phenanthroline, has transition potential of +1.25 volts.
The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1] The University of Hertfordshire maintains a database of the chemical and biological properties of these materials, [2] including their brand names and the countries and dates where and when they have been ...
Particularly well studied is [Fe(phen) 3] 2+, called "ferroin." It can be used for the photometric determination of Fe(II). [3] It is used as a redox indicator with standard potential +1.06 V. The reduced ferrous form has a deep red colour and the oxidised form is light-blue. [4] The pink complex [Ni(phen) 3] 2+ has been resolved into its Δ ...
Cerimetry or cerimetric titration, also known as cerate oximetry, is a method of volumetric chemical analysis developed by Ion Atanasiu.It is a redox titration in which an iron(II)–1,10-phenanthroline complex color change indicates the end point.
“The FCC borrowed the nutrition label model format from food products because we wanted to make basic information about broadband internet service easily recognizable and easy to understand ...
Drug labels seek to identify drug contents and to state specific instructions or warnings for administration, storage and disposal. Since the 1800s, legislation has been advocated to stipulate the formats of drug labelling due to the demand for an equitable trading platform, the need of identification of toxins and the awareness of public health.
Fluopyram is a fungicide and nematicide used in agriculture. [2] [3] It is used to control fungal diseases such as gray mold (Botrytis cinerea), powdery mildew, apple scab, Alternaria, Sclerotinia, and Monilinia.
Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2.The molecule is a complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents.
