Potassium Chromate , 50 grams for silver testing

Description

Potassium Chromate , 50 grams.  This is the purest potassium salt of chromium that you'll be able to find.  I recrystallize this a minium of 8 times to ensure that it is even more pure than what you can get from Ligma.
Wiki article; Unlike the less expensive sodium salt, the potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required. It is as an oxidizing agent in organic synthesis. It is used in qualitative inorganic analysis, e.g. as a colorimetric test for silver ion. It is also used as an indicator in precipitation titrations with silver nitrate and sodium chloride (they can be used as standard as well as titrant for each other) as potassium chromate turns red in the presence of excess of silver ions.
