Questions & Step-by-Step Solutions

What is the coordination number of the central metal ion in [Cu(NH3)4]SO4?
  • Step 1: Identify the central metal ion in the complex. In [Cu(NH3)4]SO4, the central metal ion is Cu (copper).
  • Step 2: Look at the ligands attached to the central metal ion. In this case, there are four NH3 (ammonia) ligands.
  • Step 3: Count the number of ligands attached to the central metal ion. There are 4 ammonia ligands.
  • Step 4: The coordination number is defined as the number of ligands directly bonded to the central metal ion.
  • Step 5: Since there are 4 ammonia ligands, the coordination number of the copper ion is 4.
