Question

The compound Cr(OH)3 is very insoluble in water; therefore, electrochemical methods must be used to determine its Ksp. Given the reduction of Cr(OH)3(s) to Cr(s) and hydroxide ions has a standard reduction potential of –1.48 V, calculate the solubility product, Ksp, of Cr(OH)3 at 25 °C. Additional half-reactions and standard reduction potentials can be found here.
