Question

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?
0 C
го
i. It is an endothermic reaction
ii. It is an exothermic reaction
ill. The pH of the resulting solution will be
more than seven
iv. The pH of the resulting solution will be
less than seven
​

Answer 1

Answer:

i,iii are correct.

Explanation:

It is exothermic reaction because heat is released.

Calcium hydroxide is a base. so the pH value is more than 7.

I hope it helped you :)
