Question
In the silver mirror test for aldehydes, Tollen's reagent acts as the mild oxidizing agent. What is the coordination number of the central silver ($Ag$) atom in the active complex ion present in Tollen's reagent?
Answer: 2
💡 Solution & Explanation
Tollen's reagent is an ammoniacal silver nitrate solution containing the diamminesilver(I) complex ion, $[Ag(NH_3)_2]^+$. The central silver ion ($Ag^+$) is coordinated linearly to exactly two ammonia ($NH_3$) ligands, giving it a coordination number of 2.
