Which of the following indicator is used in bromatometry?

Option b) Methyl orange is used in bromatometry titration. In bromatometry, we titrate with the help of potassium bromate, hence the name. It is used for the determination of phenol for quantitative and efficient purposes. The process is based upon the changing color of the indicator i.e. Methyl orange.

What is Bromatometry in pharmaceutical analysis?

Bromatometry is a titration process in which the bromination of a chemical indicator is observed. Potassium bromate alone can be used for the analysis of organoarsenicals.

What is cerimetry in pharmaceutical analysis?

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 (ferroin) color change indicates the end point.

Which titrant used in Bromatometry?

Bromometry uses bromine titrant.

Which oxidizing is used in bromatometry?

Answer. Bromatometry is a titration process in which the bromination of a chemical indicator is observed. Potassium bromate alone can be used for the analysis of organoarsenicals.

What are Metallochromic indicators?

Metallochl’Omic indicators are defined as organic dyes exhibiting marked acido-basic colour changes and containing a grouping capable of chelate bond formation directly joined to the conjugated system of the dye.

Which oxidizing agent is used in bromatometry?

potassium bromate
employed potassium bromate as an oxidising agent is called bromatometry.

Which indicator is used in cerimetry?

The use of nickel phthalocyanine sulphonic acid (Ni-PS) as an internal indicator in the cerimetric titration of iron(II) has been investigated. 0.2 ml of a 0.05% solution of the dye serves well as a redox indicator in 50 ml of the titration mixture. The colour change at the end point is from blue to violet.

What is the colour of ferroin indicator?

Concentration: 0.025M Composition: Water 97.84%, 1,10-Phenanthroline Monohydrate 1.47%, Ferrous Sulfate Heptahydrate 0.69% Boiling Point: Approximately 100°C Density: 1.01 Melting Point: Approximately 0°C Color: Dark red liquid Physical State: Liquid Solubility Information: Miscible …

What is Cerimetry give its application?

Cerimetry or cerimetric titration, also known as cerate oximetry, is a method of volumetric chemical analysis developed by Ion Atanasiu. Since cerimetry is linked to the Fe3+/Fe2+ redox pair, it can be used for analyses of nonstoichiometric levels that either oxidize Fe2+ or reduce Fe3+.

Is EBT a Metallochromic indicator?

Eriochrome Black T (EBT), one of the metallochromic indicators whose electrochemical behavior was studied at carbon paste electrode by cyclic voltammetry.

How many types of complexometric titration are there?

Direct titration: the cations are titrated directly with standard solution EDTA using eriochrome black T as the indicator. Back titration: a known excess of standard solution EDTA is added to the solution containing the analyte.
