The correct Answer is:
To solve the question regarding the two statements about ethylene glycol and its properties, we will analyze each statement step by step. ### Step 1: Analyze Statement 1 **Statement 1:** "The addition of ethylene glycol to water lowers the freezing point of water, therefore, it is used as an antifreeze substance." - **Explanation:** Ethylene glycol is known to lower the freezing point of water when added. This phenomenon is due to the colligative properties of solutions, which depend on the number of solute particles in a solvent. Ethylene glycol, being a non-volatile solute, disrupts the formation of ice crystals, thus lowering the freezing point of the solution. This property makes it effective as an antifreeze. ### Step 2: Analyze Statement 2 **Statement 2:** "Ethylene glycol is soluble in water." - **Explanation:** Ethylene glycol has hydroxyl (–OH) groups in its structure, which allows it to form hydrogen bonds with water molecules. This interaction makes ethylene glycol highly soluble in water, resulting in a homogeneous solution when mixed. ### Step 3: Determine the Relationship Between the Statements - Both statements are true. The first statement correctly describes the effect of ethylene glycol on the freezing point of water and its use as an antifreeze. The second statement accurately states that ethylene glycol is soluble in water. ### Step 4: Evaluate the Explanation - While both statements are true, Statement 2 does not serve as a direct explanation for Statement 1. The solubility of ethylene glycol in water is a separate property that does not explain why it lowers the freezing point. ### Conclusion - Therefore, the correct answer is: **Both statements are true, but Statement 2 is not the correct explanation for Statement 1.** ---
