Question

solid calcium oxide reacts vigorously with water to form calcium hydroxide accompanied by the 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?

Answer 1

Answer:

The first statement is correct because in second statement it is limestone which is produced not the lime water. The chemical equation of first statement is as follows

CaO+H2O=Ca(OH)2

Explanation:

Answer 2

Answer:

(c) (i) and (iv) is the correct answer.

Explanation:

Because when we Calcium oxide in water it release High amount of Heat.

And the slake is a basic substance. Calcium Hydroxide (Ca(OH)2) or slaked lime is a base because in aqueous solution of slaked lime there are hydroxide ions available due to the dissociation of electrolyte (Ca(OH)2).
