Question

What is the equilibrium Pb²⁺ concentration when 2.61 L of a 0.103 M lead acetate solution are mixed with 2.82 L of a 0.370 M ammonium bromidesolution?

[Pb²⁺] =  M

The solubility of AgCl in water is  1.34×10^-5 M, but increases in the presence of thiosulfate ion. Calculate the solubility of AgCl when the solid is added to a solution that is 0.520 M in thiosulfate ion. For AgCl, K_sp = 1.80×10^-10 and for Ag(S₂O₃)₂^3-, K_f = 2.00×10¹³.

Solubility =  M

Answer 1

we know, Ksp of lead boumide, PbBr2 = 6:60x10° (837 = (0.340x2:82) C 0.103) 52:61) 2.61+ 2.822 11043 -0.268 5143 -0.142 m 3. We know that Ksp = (+) (B7) P124 kap 6160x106 0142 1 12+ = 4,64X165m we know that, Keq = Kgp ХК = 1180x100x2x1013 = 3600 Agu+ 25703 -A9 (5,03)J+cl- 0.5200 0.520-27 134X105 134X10S +X- 2
