The correct Answer is:
To analyze the given statements, we will break down the assertions and reasons provided in the question step by step. ### Step 1: Understand Statement 1 **Statement 1:** "Colloidal solution is electrically neutral." - Colloidal solutions consist of tiny particles (1 to 1000 nanometers) dispersed in a medium. - These particles can carry charges, but in a stable colloidal solution, the overall charge is neutral due to the balance of positive and negative charges present in the system. ### Step 2: Understand Statement 2 **Statement 2:** "Due to the similar nature of the charge carried by the dispersed phase particles, they repel each other and do not combine to form bigger particles." - Dispersed phase particles in a colloidal solution often carry the same type of charge (either all positive or all negative). - This similar charge leads to electrostatic repulsion between the particles, preventing them from aggregating into larger particles. ### Step 3: Evaluate the Relationship Between the Statements - Both statements are true: - Statement 1 is true because colloidal solutions are indeed electrically neutral. - Statement 2 is also true because the similar charges on the dispersed particles cause them to repel each other. ### Step 4: Determine if Statement 2 Explains Statement 1 - While both statements are true, Statement 2 does not provide a direct explanation for why colloidal solutions are electrically neutral. Instead, it explains the behavior of the particles in the colloidal solution. - The neutrality of the colloidal solution is due to the balance of charges, not merely the repulsion of similarly charged particles. ### Conclusion - Both statements are true, but Statement 2 is not the correct explanation for Statement 1. Thus, the correct answer is: **Both statements are true, but Statement 2 is not the correct explanation of Statement 1.** ### Final Answer - **Option 2** is the correct choice. ---
