Match the common chemical substances in List-I with their primary applications in daily life and industry in List-II. Which of the following options represents the correct pairing of each substance with its application?
- Quicklime ()Essential raw material in cement manufacturing
- Milk of Magnesia ()Antacid used to relieve stomach acidity
- Baking Soda ()Leavening agent in baking and component of soda-acid fire extinguishers
- Gypsum ()Additive used to retard the initial setting time of cement
Answer
Quicklime matches with cement manufacturing; Milk of Magnesia matches with antacid application; Baking soda matches with leavening agent and fire extinguisher; Gypsum matches with retarding cement setting time.
Each chemical substance is correctly paired with its specific real-world application based on its chemical properties: Quicklime in cement making, Milk of Magnesia as an antacid, Baking soda in food/fire safety, and Gypsum for delaying cement hardening.
