A coordination compound of Cu²⁺ can be described as Cu(NH₃)_xSO₄ and is known to contain 29.9% NH₃. What is the value of x?

Question

Quizplus · Accepted Answer

The formula of the given complex can be rewritten as Cu(NH3)4S2. Now, the complex contains 29.9% NH3, which means it also contains 70.1% of the other ligands, which are S2. The formula of the complex implies that there are two S2 ligands, so the total number of ligands is 6 (4 NH3 + 2 S2). Therefore, the value of x is 6 - 2 - 1 (for the Cu) = 3.
