Read the following statements:I. When a red litmus paper is dipped into the reaction mixture of a saponification reaction, it turns blue and the reaction is exothermic.II. When a blue litmus paper is dipped into the reaction mixture of a saponification reaction, its colour does not change and the reaction is exothermic.III. When a red litmus paper is dipped into the reaction mixture of a saponification reaction, its colour does not change and the reaction is endothermic.IV. When a blue litmus paper is dipped into the reaction mixture of a saponification reaction, its colour does not change and the reaction is endothermic.Which of the above statements are correct?(a) I and II(b) II and III(c) III and IV(d) I and IV
Correct Answer: (a) I and II
Explanation: Soap solution is basic in nature because it is formed from a strong base NaOH. Hence it turns red litmus paper blue and does not change the color of blue litmus paper. The saponification reaction is exothermic in nature. Hence, the correct statements are I and II.
