Cr3+ is used in the tanning of leather. Cr(VI), as dichromate ion ( Cr2O7^2-) is much more toxic that Cr3+. If the excess of Cr3+ is discharged into a waste stream that is saturated with atmospheric oxygen at the pH of 6.0, would there be a significant conversion of Cr3+ to dichromate at equilibrium? Present numerical results to justify your conclusion.
