Concept explainers
(a)
Interpretation:
To determine the formula of diamminetetraaquachromium(II) chloride.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The
A ligand is an atom or a group of atoms or an anion that has an unshared pair of electrons and thus it can act as a Lewis base. It can donate its pair of electrons to the metal atom to form a coordinate bond with the transition metal atom.
(b)
Interpretation:
To determine the formula of tetrachlorosulfatocadmium(III).
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.
