Question

while studying the sapublication reaction what you observe when you mix an equal amount of colourless vegetable oil and 20 percent of the aqueous solution of Naoh in a beaker

Answer 1

Answer:

Explanation:

While studying the saponification reaction, when you mix an equal amount of colourless vegetable oil and 20% aqueous solution of NaOH in a beaker, the beaker becomes hot outside because the reaction that takes place is an exothermic reaction.

Answer 2

Complete question:

While studying the saponification reaction, what do you observe when you mix an equal amount of colorless vegetable oil and 20% aqueous solution of NaOH in a beaker?

Answer:

While studying the saponification reaction, we observe the outer surface of the beaker has becomes cold.

Explanation:

• Saponification is a endothermic reaction which means in this process the reaction absorbs heat from the environment.
• This makes the surface of the beaker cold.

Detailed explanation:

• Here, the saponification reaction takes place between vegetable oil, sodium hydroxide and ethanol. Here, alkaline hydrolysis takes place and sodium salt of fatty acid is formed.
• Now, the beaker surface becomes cold and it heated to form soap.
• All the excess components such as ethanol, NaOH and glycerol is removed and now we get soap.
• Later, the soap is dissolved in salt water and it is later cooled to form complete soap cake.
