Question:

2 Copper (Cu) + 1 Ammonia (NH3)

Solution: Cu(NH3)4(OH)2
Chemical Equation: 2Cu + 8NH3 + 2H2O + O2 → 2Cu(NH3)4(OH)2
Explanation: The reaction between copper and ammonia in the presence of oxygen and water results in the formation of tetraamminecopper(II) hydroxide, a deep blue complex. 🔵 This reaction is a classic example of a coordination complex formation, where the copper ion (Cu²⁺) acts as a Lewis acid and accepts electron pairs from the ammonia molecules (NH3) acting as Lewis bases. 🤝 The reaction also involves the oxidation of copper from Cu(0) to Cu(II) by oxygen. 🌬️
