Which of the following statements is correct for complex formed by combination of one mole of PtCl_(4) and four mole NH_(3) ?

Which of the following statements is correct with regard to complex ion ? . (a) complex ion consists of a central ion bonded to two or more donor ions or molecules usually does not dissociate into simple ions or molecules even in a solution and exhibits properties different from its constituent ions or molecules (b) The donor ions and molecues which coordinate with the central atom or ion a complex are called ligands The sum of the number of electrons pressent in the central metal ion or atom and those donated by the ligands is called the effective atomic number of the central metal aton and this number is usually the same as the atomic number of the next higher noble gas (d) All of these .

Double salts are addition compounds which lose their identify in aqueous solution whereas complexes which are also addition compounds do not lose their identify in aqueous solution. The coordination compounds show isomerism and find application in photography , qualitative analysis, metallurgy, water purification and in the treatment of various diseases.

Which of the following statment is incorrect ?

On the basic of stability of complex ion in the solution, complexes may be of two types, perfect and imperfect complexes. The stability depends upon the extent of dissociation which in turn depends upon charge on central metal atom, basic nature of ligand, chelation, and nature of metal ion and ligand according to HSAB principle.
