Question

Which indicator is used in bromatometry titration​

Answer 1

51015, 51040, 51045, 51050 and 51175 respectively), Cresyl Fast Violet Acetate (CFVA), and Resazurin (RSZ) as indicators in the bromatometric titrations of the analytes, iron(II), arsenic(III), antimony(III), thallium(I) and hydrazine in sulphuric and hydrochloric acid media.

Answer 2

Bromometry is a titration process in which the bromination of a chemical indicator is observed.

Explanation:

• Potassium bromate alone can be used for the analysis of organoarsenic.
• As a titrant, sodium thiosulfate is commonly used, and as an indicator starch, with an iodine compound (either iodate or iodide), depending on the desired reaction.
• Serimetry or serimetric titration, also known as Serrate oximetry, is a method of volumetric chemical analysis developed by Ion Atanasiou.
• This is a redox titration in which an iron(II)-1,10-phenanthroline complex (ferroin) color change indicates the end point.

Types of Redox Titration

• Bromometry uses bromine titrant.
• Cerimetry uses cerium(IV) salt.
• Dichromate uses potassium dichromate.
• Iodometry uses iodine(I2).
• Permanganometry uses potassium permanganate.
