Question 3 Look at sample problem 19.14 in the 8th ed Silberberg book. Make sure to carry additional sigfigs in early calculations steps to avoid huge error propagation. You should round it up in the final step according to the request of the question. In black-and-white film developing, excess AgBr is removed from a film negative with "hypo," an aqueous solution of sodium thiosulfate (Na2S₂O3), which forms the complex ion Ag(S₂O3)2³-. Calculate the solubility of AgBr in 0.58 M hypo. Kf of Ag(S₂03)2³- is 4.7×1013 and Ksp of AgBr is 5.0×10-13 Write the overall equation for the Ksp of AgBr and then the Kf of Ag(S₂O3)2³, add the 2 equations thus multiplying the two K values. Do an ICE chart, Enter a number to 2 decimal places.
