Description and Uses

Potassium rhodizonate is suitable reagent for the preparation of staining solution used in the rhodizonate test for the detection of lead. It is suitable reagent used in the preparation of barium, thallium, ammonium and silver salts rhodizonic acid by metathesis in aqueous solution.
It may be used in the following studies:

To cocrystallize plutonium and radium from urine in the plutonium and radium assay of urine.
As a dye in the spectrophotometric determination of sulfate ion.
To determine the acid dissociation constants of rhodizonic acid by pH potentiometric titration of potassium rhodizonate with standardized HCl.
As a staining agent for plagioclase in the petrographic study.
