Options

A. For coloured ppt./Black ppt
B. For coloured solution.
C. for clear/colourless solution
D. For white ppt.

Answer

To solve the given reaction step by step, we will analyze the reactants, products, and the type of reaction involved.

### Step 1: Identify the Reactants
The reactants in the reaction are:
- Silver nitrate (AgNO₃)
- Sodium hydroxide (NaOH)

### Step 2: Write the Reaction
The reaction can be written as:
\[ 2 \text{AgNO}_3 + 2 \text{NaOH} \rightarrow \text{Ag}_2\text{O} + 2 \text{NaNO}_3 + \text{H}_2\text{O} \]

### Step 3: Identify the Products
The products formed from the reaction are:
- Silver oxide (Ag₂O)
- Sodium nitrate (NaNO₃)
- Water (H₂O)

### Step 4: Balancing the Reaction
The reaction is already balanced as we have:
- 2 Ag from 2 AgNO₃
- 2 Na from 2 NaOH
- 2 NO₃ from 2 AgNO₃
- 2 Na from 2 NaNO₃
- 1 O from Ag₂O and 1 O from H₂O

### Step 5: Determine the Type of Reaction
This reaction is a double displacement reaction (also known as a precipitation reaction) because the ions in the reactants exchange partners to form new products.

### Step 6: Identify the Color of the Precipitate
In this reaction, silver oxide (Ag₂O) is formed, which is known to be a black or brown precipitate. This indicates that the reaction produces a colored precipitate.

### Conclusion
The correct option for the question regarding the nature of the product formed is that a black precipitate of silver oxide is produced.
