Formula of Complex Hexamminecobalt (III) Chloride Sulphate

The correct answer is 'A' which represents the formula [Co(NH3)6]ClSO4. Let's break down the answer into the following headings:

I. Understanding the Formula
II. Explanation of the Formula
III. Conclusion

I. Understanding the Formula
Before we dive into the formula, let's understand some key terms:
- Complex: A molecule or ion formed by the combination of a metal ion with a ligand (a molecule or ion that can donate a pair of electrons to the metal ion)
- Hexamminecobalt (III) chloride: A complex formed by the combination of cobalt (III) ion with six ammonia molecules and one chloride ion
- Sulphate: A compound containing the sulphate ion (SO4 2-)

II. Explanation of the Formula
The given complex contains cobalt (III) ion, six ammonia molecules (NH3), one chloride ion (Cl-), and one sulphate ion (SO4 2-). The cobalt (III) ion is coordinated by six ammonia molecules forming an octahedral complex. The chloride ion and sulphate ion occupy the remaining two positions of the octahedral complex. Therefore, the formula of the complex is [Co(NH3)6]ClSO4.

III. Conclusion
In conclusion, the formula of the complex hexamminecobalt (III) chloride sulphate is [Co(NH3)6]ClSO4. The complex contains cobalt (III) ion coordinated by six ammonia molecules, one chloride ion, and one sulphate ion.
