The process of saponification involves the hydrolysis of fats/oils with:
A. Strong base
B. Water alone
C. Alcohol
D. Dilute acid
Answer: Option A
Solution (By JKExamLibrary)
Saponification is the alkaline hydrolysis of fats or oils (which are esters of fatty acids) using a strong base like NaOH or KOH. This reaction produces glycerol and the sodium or potassium salts of fatty acids, which are soaps. It is an irreversible reaction.
Explanation:
Calorific value is determined using a bomb calorimeter, where a known mass of fuel is burnt in excess oxygen in a sealed bomb, and the heat released is absorbed by a known mass of water. Temperature rise is measured. Corrections for cooling, wire, and acid formation are applied. Units: kJ/kg or kJ/mol. The bomb calorimeter works at constant volume.
Explanation:
Single superphosphate (SSP) is manufactured by treating rock phosphate with sulfuric acid. The resulting product is a mixture of calcium dihydrogen phosphate (Ca(H2PO4)2), which is the actual fertilizer providing soluble phosphorus, and calcium sulfate (CaSO4, gypsum), which is an inactive filler.
