- What chemical tests would you use to distinguish between (a) [Co(NH3)5 Br] [SO4] and [Co(NH3) 5 (SO4)] Br, and (b) [CrCl₂ (OH₂)4] Cl-2H₂O and [CrCl(OH₂)5]Cl₂ H₂O? (c) What is the relationship between these pairs of compounds? (d) What isomers are possible for [CrCl₂ (OH₂)4]?arrow_forward[CuCl4]2− is green. [Cu(H2O)6]2+is blue. Which absorbs higher-energy photons? Which is predicted to have a larger crystal field splitting?arrow_forward[Co(H2O)6]2+ (aq) + 4 Cl-(aq )⇆ [CoCl4]2-(aq) + 6 H2O 3. Does the value of the equilibrium constant (K) for this reaction increase, decrease, or remain the same as the concentration of chloride increases? Explain your answer incorporating the definition of an equilibrium constant.arrow_forward
- Which is more acidic and why? [Fe(H2O)6]2+ or [Fe(NH3)(H2O)5]2+arrow_forward3. Consider the blue-colored compound, [Cr(H₂O)]3³ and the yellow-colored compound, [Cr(CN)6]³. Calculate their magnetic moments and discuss their magnetic properties and their color.arrow_forwardDraw diagrams showing the structures of and name all the stereoisomers of [CoCl2(en)2]Cl.arrow_forward
- Explain the origin of the color of K3[Fe(C2O4)3] ∙3H2O.arrow_forwardIn acidic aqueous solution, the purple complex ion Co(NH3)5Br2+ undergoes a slow reaction in which the bromide ion is replaced by a water molecule, yielding the pinkish-orange complex ion : Co(NH3)5(H2O)3+ Co(NH3)5Br2+Purple(aq)+H2O(l) → Co(NH3)5(H2O)3+Pinkish−orange(aq)+Br−(aq)The reaction is first order in Co(NH3)5Br2+, the rate constant at 25 ∘C is 6.3×10−6 s−1, and the initial concentration of Co(NH3)5Br2+ is 0.100 MM. What is its molarity after a reaction time of 19.0 h ? How many hours are required for 85 %% of the Co(NH3)5Br2+ to react?arrow_forward<p>Determine if either isomer of [Fe(CO)3Cl3] is optically active.arrow_forward
