In the determination of K and G for an Fe complex lab, What would be the effect on the value of the molar concentration of FeSCN2+ at equilibrium,if the stock solution used to prepare the standard curve had not reacted comp
Look at sample problem 19.14 in the 8th ed Silberberg book. In black-and-white film developing, excess AgBr is removed from a film negative with "hypo," an aqueous solution of sodium thiosulfate (Na2S203), which forms the complex ion Ag(S203)23-. Calculate the solubility of AgBr in 0.67 M hypo. Kf of Ag(S203)23- is 4.7x1013 and Kgp of AgBr is 5.0x10-13 Write the overall equation for the Ksp of AgBr and then the Kf of Ag(S203)23-, add the 2 equations thus multiplying the two K values. Do an ICE chart, Enter a number to 2 decimal places.
