An excess of $AgNO_3$ is added to $100 \ mL$ of a $0.01 \ M$ solution of dichlorotetraaqua-chromium$(III)$ chloride. The number of moles of $AgCl$ precipitated would be

Explain the classification of ligands on the basis of their denticity.

An aqueous solution of the complex $[Cu(NH_3)_4]SO_4$ gives the test for:

Given below are two statements :
Statement $I$ : $[Co(NH_3)_6]^{3+}$ is a homoleptic complex whereas $[Co(NH_3)_4 Cl_2]^{+}$ is a heteroleptic complex.
Statement $II$ : Complex $[Co(NH_3)_6]^{3+}$ has only one kind of ligands but $[Co(NH_3)_4 Cl_2]^{+}$ has more than one kind of ligands.
In the light of the above statements,choose the correct answer from the options given below.

The primary valency and secondary valency of the central metal ion and the number of total ions produced in an aqueous solution for the $K[Co(OX)_2(NH_3)_2]$ complex are,respectively, . . . . . . .
