Explanation: Slaking of lime is an exothermic reaction because a large amount of heat is produced during the reaction. The heat can be felt by touching the beaker from the 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.
