The correct Answer is:
To solve the question, we need to analyze both statements provided and determine their validity. ### Step 1: Analyze Statement 1 **Statement 1:** When AgNO₃ is treated with excess of KI, colloidal particles get attracted towards the anode. - When silver nitrate (AgNO₃) is mixed with potassium iodide (KI), a reaction occurs that leads to the formation of silver iodide (AgI), which is a colloidal precipitate. - In the presence of excess KI, the AgI can form a soluble complex with the iodide ions (I⁻), resulting in the formation of a negatively charged colloidal solution. - Since the colloidal particles are negatively charged, they will be attracted to the anode (positive electrode) when an electric field is applied. **Conclusion for Statement 1:** This statement is true. ### Step 2: Analyze Statement 2 **Statement 2:** Colloidal particles adsorb common ions and thus become charged. - While it is true that colloidal particles can become charged, the explanation provided in this statement is misleading. - Colloidal particles can become charged through various mechanisms, including the adsorption of ions from the surrounding medium. However, the statement does not specify that it is the common ions that cause this charging. - The charging of colloidal particles is a more complex phenomenon and is not solely dependent on the adsorption of common ions. **Conclusion for Statement 2:** This statement is false. ### Final Conclusion: - **Statement 1 is true.** - **Statement 2 is false.** Given the analysis, the correct option is that Statement 1 is true and Statement 2 is false.
