The given observation that
Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of
The Metal ion which is positively charged functions as a Lewis acid. Lewis base or the ligand has one or more lone pairs of electrons. For example, Cu2+, which is a highly charged and small metal ion having a significant tendency to function as Lewis acids, consequently exhibiting the greatest affinity to form complex ions.
The development of a complexion is a stepwise procedure, and every step has its equilibrium constant. When two of the equations are added together, the equilibrium constants multiply.

Interpretation:
In the given observation the reason by which Agl will dissolve in an aqueous solution of sodium thiosulfate should be determined in terms of complex-ion formation.
Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of chemical equilibrium. A complexion comprises of a ligand and a metal ion as a result of an interaction of Lewis acid-base.

- Two different compounds are known with the formula Pd(py)2Cl2, but there is only one compound with the formula Zn(py)2Cl2. The symbol py is for pyridine, a mono-dentate ligand. Explain the differences in the Pd and Zncompounds.arrow_forwardhas a crystal field splitting energy, o, of 2.60102 kJ/mol. What is the wavelength responsible for this energy?arrow_forwarda. In the absorption spectrum of the complex ion Cr(NCS)63, there is a band corresponding to the absorption of a photon of light with an energy of 1.75 104 cm-1. Given 1 cm1 = 1.986 1023 J, what is the wavelength of this photon? b. The CrNC bond angle in Cr(NCS)63 is predicted to be 180. What is the hybridization of the N atom in the Ncs- ligand when a Lewis acid-base reaction occurs between Cr3+ and NCs- that would give a 180 CrNC bond angle? Cr(NCS)63 undergoes substitution by ethylenediamine (en) according to the equation Cr(NCS)63+2enCr(NCS)2(en)2++4NCS Does Cr(NCS)2(en)2+ exhibit geometric isomerism? Does Cr(NCS)2(en)2+ exhibit optical isomerism?arrow_forward
- Would you expect salts of the gold(I) ion, Au+, to be colored? Explain.arrow_forwardFour different octahedral chromium coordination compounds exist that all have the same oxidation state for chromium and have H2O and Cl as the ligands and counterions. When 1 mole of each of the four compounds is dissolved in water, how many moles of silver chloride will precipitate upon addition of excess AgNO3?arrow_forwardFive-coordinate coordination complexes are known, including [CuCl5]3 and [Ni(CN)5]3. Write the structuralformulas and identify a plausible geometry for thesecomplexes.arrow_forward
