estimation of barium as barium chromate
Barium chromate is used as a pigment, oxidizing agent, colorant in glass, and sulfate scavenger in chromium electroplating baths, ceramics, and porcelain. Barium chloride is added to potassium chromate What will be color of the final solution? Is it possible that your potassium chromate was made using tap water, or that your glassware wasn't cleaned with distilled water prior to use? I got a white precipitate in an opaque yellow solution and I was told that the white precipitate was $\ce{BaCrO_4}$ but while searching on Internet I found that its color is yellow, and that the $\ce{KNO_{3(aq)}}$ is white, so my question is what is true?

What are the chemical reactions that have HNO3 (nitric acid) as product? The varying sizes of the pores allow the growth to be controlled and cause the shapes to be reproducible. [10] Due to its moderate tinting strength lemon yellow was not employed very frequently in oil painting. Hot-dip vs Cold Galvanizing: Whats the Difference? or what causes the color of the final solution? 253.33g MIC Corrosion: How Can Microorganisms Eat Holes in a Metal? The yellow color originates from $\ce {CrO4^ {2-}}$, and a small amount of finely divided precipitate may look white at first sight (namely when the yellow color of the solution is more intense), when it is actually pale-yellow (it can look like this ). precipitates are filtered, and weighed.

Donating to our cause, you are not only help supporting this website going on, but also More than 99.7% of the barium can be precipitated as the chromate, with less than 0.6% of the strontium, when the two ions are in equal molar concentration. For example, barium chromate can be precipitated in the presence of strontium and lead by first complexing the metal ions at .
