Remember you can write, as an example of exothermic reaction is “Slaking of lime” because a large amount of heat is produced during the reaction. We can feel the heat energy by touching the beaker from the outside. It easily turns indicators (red litmus) solution to blue and hence proves that it to be a basic solution. Hence the pH of the solution will be more than 7. You should go with the option [B] as an answer.
(C) Areolar tissue Areolar tissue is a loose and cellular connectivity tissue. It is a matrix consisting of two types of fibers i.e. white collagen fibers (which turn into gelatin when boiled in water) and yellow elastic fibers or elastin.

See lessSodium 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 a solution called lime water. Which among the following is true about slaking of lime and the solution formed?
