- Platinum(II) forms many complexes, among them those with the following ligands. Give the formula and charge of each complex. (a) two ammonia molecules and one oxalate ion (C2O42-) (b) two ammonia molecules, one thiocyanate ion (SCN-), and one bromide ion (c) one ethylenediamine molecule and two nitrite ionsarrow_forwardAn aqueous solution of [Rh(C2O4)3]3− is yellow. Predict the approximate wavelength and predominant color of light absorbed by the complex.arrow_forwardCobalt (II) carbonate is slightly soluble in water (Ksp = 1.0 x 10-10). In the presence of an excess of ammonia, Co²+ forms a complex with six ammonia ligands that is somewhat favorable (K₁ = 1.3 x 105). What is the value of the equilibrium constant (Koverall) for the overall reaction that occurs? COCO3 (s) +6 NH3 (aq) → Co(NH)32+ (aq) + CO32- (aq) 1.3 x 10-5 3.6 x 10² 7.7 x 10-16 1.3 x 105 1.0 x 10-10arrow_forward
- 4. Consider the following reaction: [ZnCl4]² +4 OH → [Zn(OH)4]² +4 CI If the reaction is spontaneous, then which of the following is true? (A) Chloride is a more labile ligand than hydroxide in zinc complexes (B) Hydroxide is a more labile ligand than chloride in zinc complexes (C) Chloride is a more inert ligand than hydroxide in zinc complexes (D) Hydroxide and chloride are equally labile in zinc complexesarrow_forwardA complex M(SCN)2 can be produced from an aqueous equilibrium in which the M2+ ion is mixed with thiocyanate ion. A solution containing initial concentrations of M2+ and SCN− are 0.000100 M and 0.000250 M respectively has an equilibrium concentration of M(SCN)2 of 2.00 × 10−5 M.What are the equilibrium concentrations of the two starting ions and what is the value of the equilibrium constant?[M2+] = [SCN−] = Kc =arrow_forwardFor [Co(NH3)6]3+ , Kf has a value of 5.00 × 1031. Calculate the concentration of free, uncomplexed Co3+ ions in a solution that contains a total of 0.160 mol/L cobalt III ions and an equilibrium concentration of 0.50 M NH3.arrow_forward
