On passing ammonia gas through a copper sulphate solution _____ precipitate is formed. [greenish yellow/ pale blue]

Explanation

To answer the question, we need to analyze the reaction that occurs when ammonia gas is passed through a copper sulfate solution. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Reactants
The reactants in this reaction are ammonia gas (NH3) and copper sulfate solution (CuSO4).

### Step 2: Understand the Reaction
When ammonia gas is introduced to copper sulfate solution, a chemical reaction occurs. Ammonia can react with copper ions (Cu²⁺) present in the copper sulfate solution.
