Question

Write the formula of Tetra-aminoaquachlorido-cobalt (III) chloride.

Hint:

In coordination complexes, the metal ion is followed by the ligands in brackets, and the charge is balanced with counterions outside the brackets.

Answer 1

Step 1: Understand the compound's structure.
The name {Tetra-aminoaquachlorido-cobalt (III) chloride} refers to a coordination complex where cobalt (III) is the central metal ion. The ligand names give us the following: - Tetra-amino: Four ammine groups (\( NH_3 \)) - Aqua: Water molecule (\( H_2O \)) - Chlorido: Chlorine ion (\( Cl^- \))
Step 2: Formulate the compound.
The metal ion is Cobalt(III) (\( Co^{3+} \)). The ligands are attached to the cobalt ion, and the formula is written as: \[ [Co(NH_3)_4(H_2O)(Cl)]Cl_2 \]
Final Answer: \[ \boxed{[Co(NH_3)_4(H_2O)(Cl)]Cl_2} \]
