The secondary valency is non-ionisable and cannot be precipitated because it form coordinate bond with the metal atom. For example in coordination compound Cl4 , the secondary valencies are 6 for Pt4+, so in this Pt4+ is satisfied by chlorine and ammonia molecules. What is the secondary valency of thisRead More →

the primary valency is non-directional because the metal atom works towards satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies. What is meant by primary valency is Ionisable? Primary valency is knownRead More →
