Question

In aqueous solution cobalt(II) ion is surrounded by 4 water molecules and has a light pink color. When high concentrations of chloride ion are introduced, a cobalt-chloride complex ion forms that has a distinctive blue color. One way to represent this equilibrium is: Cocl,"(aq) = Co2+ (aq) + 4 CI" (aq) An experiment was run to demonstrate that a dynamic equilibrium exists between these two ions. Starting with a special form of CoC142(aq) where one of the chloride ions was isotopically labeled (PCI used instead of the naturally occuring isotopes), the system was then allowed to reach equilibrium. ci 317 Co LCI CU Indicate with Y (yes) or N (no) which of the structures below show that the forward or reverse reactions occur for this chemical system. "CICI CI 72

Answer 1

Pg-01 Answer:- Given Equation : The Equilibrium is to represent " The one way (coolumns) = company talian) 36,72 C C reaction a In This indicate with y (res) or N (no) which of the structures below show That the forward or reversed occur for this chemical System. forward direction. normal chloride * chloride ion dissociate from the in complex * while in combining I to to form complex, both and isotopic chloride can combine. that backward reaction B and c The structures taking place. A - N (no) B-y (yes) y (yes) D N (no)

" the one way to represent the Equilibrium is NzQu(a) = 2o, (2) of the reversed reaction a) In This indicate with y (res) or N (no) which structures below : Show That the forward or Artur for this chemical System. - Here starting with a special form of Naou where one of the oxygens was isotopically labeled (18o instead of "%) The then system was allowed to facilibrium. reach - the structures B and C That backward reaction taking place A-NC NO) B - Y (Yes ) czy ( Yes ON ( No ) * In starting material only one 018 isotope is available. If it I dissociate and recouple only two 018 isotope zou is possible Shucture with three and four Dig is hpe labelled wou's not possible. Therefore Yes for strwtuve Bands and no for Al D.
