Question

26. Solid calcium oxide reacts vigorously with water to form calcium hydroxide accompanied by liberation of heat. This process is called slaking of lime.Calcium hydroxide dissolves in water to form its solution called lime water. Which among the following is (are) true about slaking of lime and the solution formed? i) It is an endothermic reaction ii) It is an exothermic reaction iii) The P" of the resulting solution will be more than seven. iv) The P" of the resulting solution will be less than seven A) (i) and (ii) B) (ii) and (iii) C) (i) and (iv) D) (ii) only​

Answer 1

Answer:

B

Explanation:

The energy produced during the reaction is released as the form of heat energy and that is why the slaking of lime is an exothermic reaction.

high calcium quicklime produces a hydrated lime containing generally 72 to 74 percent calcium oxide and 23 to 24 percent chemically combined water.
