Question:

In order to study saponification reaction we first prepare 20?

endothermic and the solution is acidic

exothermic and the solution is alkaline

endothermic and the solution is alkaline

exothermic and the solution is acidic

Solution:

The saponification reaction is exothermic in nature, because heat is liberated during the process. The soap formed remains in suspension form in the mixture. Sodium hydroxide is a base and its solution in water turns red litmus blue. Hence, its solution in water is alkaline.
