What is the equation for I- titrated with the IO3 standard solution.

Full Screen O Accessibility Given 100 mL of a solution that contains 0.80 mM Ag* and 0.80 mM Cu*, can the two metals be separated by selective precipitation as the insoluble bromide salts by adding 10 mL of an 8.0 mM solution of KBr? Kso values are 6.27 x 10-9 for CuBr and 5.35 x 10-13 for AgBr. Yes, the two metals can be separated. No, the two metals cannot be separated. « Previous MacBook Air

A solution containing both Mn2+ and Cd²+ at 0.10M each is saturated with H2S gas at 25ºC and 1 atm pressure. The [H+] is adjusted with HCl to 0.30M. a) Will the sulfides of these metals precipitate under these conditions? b) Calculate the maximum concentration of Cd2+ and Mn²+ that can remain in solution. Ksp for MnS = 1.0 x 10-13 ; Ksp for CdS = 1.0 x 10-26 %3D In a saturated solution of H2S at 1 atm and 25°C, [H2S] = 0.10M %3D Ka1(H2S) = 5.7 x 10-8 ; Ka2 = 1.3 x 10-13
