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

Answer

To determine the outcome of the reaction between sodium carbonate (Na₂CO₃) and potassium nitrate (KNO₃), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this case are sodium carbonate (Na₂CO₃) and potassium nitrate (KNO₃). Both of these are salts.

### Step 2: Analyze the Nature of the Reactants
- Sodium carbonate (Na₂CO₃) is a salt derived from a strong base (NaOH) and a weak acid (H₂CO₃).
- Potassium nitrate (KNO₃) is also a salt derived from a strong base (KOH) and a strong acid (HNO₃).

### Step 3: Check for Possible Reactions
In general, when two salts are mixed in an aqueous solution, a reaction may occur if:
- A precipitate forms (an insoluble product).
- A gas is released.
- A weak electrolyte (like water) is formed.

### Step 4: Determine Solubility
Both Na₂CO₃ and KNO₃ are soluble in water. When they are mixed, they do not form any insoluble products. Therefore, no precipitate will form.

### Step 5: Conclusion
Since there is no formation of a precipitate or any other reaction, we conclude that there is no reaction between Na₂CO₃ and KNO₃. The solution remains clear and colorless.

### Final Answer
The correct option is: **Clear colorless solution**.
