The correct Answer is:
To solve the question, we need to analyze both statements provided: **Statement-1:** In fused state, calcium chloride cannot be used to dry alcohol or `NH3`. **Statement-2:** Anhydrous `CaCl2` is not a good desiccant. ### Step-by-Step Solution: 1. **Understanding Calcium Chloride:** - Calcium chloride (CaCl2) can exist in different forms: hydrated (with water) and anhydrous (without water). The anhydrous form is often used as a desiccant because it can absorb moisture from the environment. 2. **Analyzing Statement-1:** - The statement claims that in its fused state (which refers to the anhydrous form), calcium chloride cannot be used to dry alcohol or ammonia. - This is true because when anhydrous CaCl2 is used with alcohol or ammonia, it reacts with them to form complexes (e.g., CaCl2·4NH3 or CaCl2·4C2H5OH), which means it is not simply drying them but forming new compounds. 3. **Analyzing Statement-2:** - This statement claims that anhydrous CaCl2 is not a good desiccant. - This is false because anhydrous calcium chloride is indeed a good desiccant due to its hygroscopic nature, meaning it readily absorbs moisture from the air. 4. **Conclusion:** - Statement-1 is true: Anhydrous calcium chloride cannot be used to dry alcohol or ammonia because it reacts with them. - Statement-2 is false: Anhydrous calcium chloride is a good desiccant. ### Final Answer: - Statement-1 is true, and Statement-2 is false.
