Single superphosphate is manufactured commercially by reacting rock phosphate with phosphoric acid and calcium hydroxide. What is the MAIN purpose of adding phosphoric acid to the reaction?
सही उत्तर: ग) To stabilize the crystalline structure of the phosphate minerals.
Phosphoric acid provides a source of phosphate ions (H₂PO₄⁻) necessary to react with the calcium from calcium hydroxide to form the soluble calcium phosphate that constitutes the fertilizer component. The other options describe secondary reactions or stabilization attempts.

Bleaching powder (Calcium Hypochlorite) is commonly added to drinking water supplies to control bacterial growth. Its primary action relies on which chemical process?
सही उत्तर: घ) Formation of a protective film over the water’s surface.
Bleaching powder contains hypochlorite ions (OCl⁻) which are strong oxidizing agents. These oxidize and destroy the cell walls and proteins of microorganisms, effectively killing or inactivating them. The other options describe different disinfection methods.

The Haber-Bosch process for ammonia synthesis is represented by the equation: N₂(g) + 3H₂(g) ⇌ 2NH₃(g). Given that this reaction has a negative ΔH, what adjustment to the conditions would MOST effectively increase the yield of ammonia?
सही उत्तर: घ) Removing ammonia from the system.
A negative enthalpy change indicates an exothermic reaction. To shift the equilibrium towards product formation (ammonia), a decrease in temperature is most effective as it favors the forward reaction according to Le Chatelier's principle. Increased pressure also pushes for products but a catalyst will speed up BOTH reactions equally.

Alum (Potassium Aluminum Sulfate) is added to muddy water primarily due to its ability to form insoluble precipitates. Which of the following statements accurately describes this process?
सही उत्तर: घ) It coagulates colloidal particles by neutralizing surface charges.
Alum acts as a flocculant. It neutralizes the negative charge of colloidal particles, allowing them to aggregate and form larger clumps (floc) that settle out of the water due to gravity. The other options describe different mechanisms for clarifying water but are not the primary action of alum.
