Colour of Potassium Chromate

Indeed manganates are often isostructural with sulfates and chromates a fact first noted by Eilhard Mitscherlich in 1831. At the end point when all chloride ions are consumed by silver ions reddish brown colored precipitate is formed by reaction of silver ions and chromate ions.

A browse through images of chromium compounds on Wikipedia shows a whole spectrum of colours.

. The manganeseoxygen distance is 1659 pm about 3 pm longer than in permanganate. Dark red chromiumVI oxide orange-red lead chromate bright yellow sodium chromate brilliant chrome green thats chromeIII oxide light blue chromiumII chloride and violet anhydrous chromiumIII chloride. As a d 1 ion it is paramagnetic but any JahnTeller distortion is too small to be detected by X-ray.

In this method silver nitrate is used as titrant and chloride ion solution as analyte. The manganateVI ion is tetrahedral similar to sulfate or chromate. The last of these compounds shows an amazing property.

Potassium chromate is used as an indicator. Colour odour melting point boiling point solubility radioactivity and reactivity can all be used to identify a substance. Chromatography electrophoresis and field-flow fractionation are some of the instrumental methods that can be used to separate samples.

Quantitative analysis that uses mass or volume adjustments to measure quantity is known as traditional quantitative analysis. Its a direct titration method.
