Reduction of Tollons' reagent to a silver mirror is known as.............

Explanation

To solve the question "Reduction of Tollens' reagent to a silver mirror is known as.............", we will follow these steps:

### Step 1: Understand the context of the question
The question is asking about a specific reaction involving Tollens' reagent, which is commonly used to test for the presence of aldehydes.

### Step 2: Identify Tollens' reagent
Tollens' reagent is a solution of silver nitrate (AgNO₃) in ammonia (NH₃). It is used to detect aldehydes by oxidizing them while reducing silver ions to metallic silver.
