Compound Ksp AgCl 1.6 x 10-10 Ag2CrO4 1.2 x 10-12 AgBr 7.7 x 10-13 (a) Which compound will precipitate first? (b) What is the [Ag+] right before the second compound begins to precipitation? (c) Right before the third compound begins to ppt, what are the percentages of Cl-, Br and CrO42- that remain in solution?

Step 1

For AgCl: $K_{sp} = [Ag^+][Cl^-]$ $[Ag^+] = \frac{K_{sp}}{[Cl^-]} = \frac{1.6 \times 10^{-10}}{0.0010} = 1.6 \times 10^{-7} M$ For AgBr: $K_{sp} = [Ag^+][Br^-]$ $[Ag^+] = \frac{K_{sp}}{[Br^-]} = \frac{7.7 \times 10^{-13}}{0.0010} = 7.7 \times 10^{-10} M$ For Show more…
