Solid Calcium Oxide Reacts Vigorously Water Calcium Hydroxide Accompanied Liberation

Solid calcium oxide reacts vigorously with water to form calcium hydroxide accompanied by the liberation of heat. This … and (iv) D….


B – Slaking of lime is an exothermic reaction because a large amount heat is produced during the reaction. The heat can be felt by touching the beaker from outside. The resulting compound Ca(OH)2, which is also called slaked lime, turns red litmus solution to blue and hence proves it to be a basic solution. Thus, the pH of this solution will be more than seven.
