PAN is a metal indicator and colorimetric reagent for heavy metal and rare earth metal ions. This reagent is slightly soluble in acidic solutions and soluble in alkaline solutions.
PAR is a metal indicator and colorimetric reagent for heavy metal ions. The solubility of this reagent in water (5 mg per 1 ml at 1ºC) is higher than that of PAN.
