Question

During saphonification a student added 20% of NAOH and 20ml of castor oil in a flask the flask get hot what will you conclude from yhis

Answer 1

Hi there,

Answer: due to the exothermic reaction.

Explanation

NaOH is a strong base and castor oil used as fat in the preparation of soap. NaOH is used to convert fat molecules into glycerol and salts of carboxylic acid. As we know that NaOH is an alkali and it will release energy due to the exothermic reaction takes place between NaOH and castor oil.

Hope it helps you...

Answer 2

During saponification a student added 20% of NaOH and 20ml of castor oil in a flask the flask get hot what can be concluded from this is that the reaction was an exothermic one.

This implies that the sodium hydroxide added reacted vigorously with the acid producing heat.

This heat produced is the one responsible for the increase in temperature.
