## Abstract The formation of a red coloured chelate (Ξ»~max~ 455 mΞΌ) between ammonium vanadate and sodium alizarin‐3‐sulphonate has been taken advantage of, in the colorimetric determination of pentavalent vanadium on a micro‐scale. The colour formation is instantaneous and the colour intensity is c
