Sodium chromate | Na2CrO4 - PubChem

The capacity of glutathione to reduce Cr(VI) to Cr(III) in vitro was investigated.The reaction was determined spectrophotometrically by following the absorption of Cr(VI) at 370 nm. At stoichiometric conditions (molar ratio Cr(VI)/GSH of 1:3) the reduction was strongly dependent on the solution's pH. It was much slower at pH 7.4 than at pH values below 5.
