Questions & Step-by-Step Solutions
Which of the following statements is true about the complex ion [Co(NH3)6]3+?
Step 1: Identify the central metal ion in the complex. In this case, it is cobalt (Co).
Step 2: Determine the oxidation state of cobalt in the complex. The complex is [Co(NH3)6]3+, which means cobalt has a +3 charge.
Step 3: Recognize that cobalt is a transition metal, which is a category of metals in the periodic table.
Step 4: Identify the ligands in the complex. Here, NH3 (ammonia) is the ligand, and there are 6 of them.
Step 5: Calculate the coordination number, which is the number of ligands attached to the central metal ion. Since there are 6 NH3 ligands, the coordination number is 6.
