Question

While studying saponification reaction, a student measures the temperature of the reaction mixture and also finds its nature using blue/red litmus paper. On the basis of his observations the correct conclusion would be

(A) the reaction is exothermic and the reaction mixture is acidic.

(B) the reaction is endothermic and the reaction mixture is acidic.

(C) the reaction is endothermic and the reaction mixture is basic.

(D) the reaction is exothermic and the reaction mixture is basic.

Answer 1

Saponification reaction is a highly exothermic reaction. The reaction mixture of this reaction is basic in nature and hence, this will turn red litmus blue. Thus, it is basic in nature.

Hence, the correct option is D.
