Step 1:
The hydroxide nucleophiles attacks at the electrophilic C ofthe ester C=O, breaking the π bond and creating the tetrahedral intermediate.
Step 2:
The intermediate collapses, reforming the C=O
results in the loss of the leaving group the alkoxide, RO-, leading to the carboxylic acid.
Step 3:
An acid / base reaction. A very rapid equilibrium where the alkoxide,RO- functions as a base deprotonating the carboxylic acid, RCO2H, (an acidic work up would allow the carboxylic acid to be obtained from the reaction).

Why refluxing is done in saponification?
Refluxing is done in the saponification reaction to maintain a constant temperature and ensure that the reaction proceeds to completion. By heating the reaction mixture to boiling and condensing the vapors back into the reaction vessel, it helps to drive the reaction forward and speed up the formation of soap.
How long is saponification in soap?
The saponification process in soapmaking usually takes between 24 to 48 hours to complete. During this time, the oils and lye solution react to form soap through the chemical reaction of saponification. Once saponification is complete, the soap is left to cure and harden before it is ready for use.
What is the importance of saponification value of oil?
The saponification value of oil indicates the amount of base needed to saponify a certain quantity of oil, which is important in soap making to determine the amount of lye required for the saponification process. It helps ensure that the right balance of oil and lye is used to create a stable and effective soap product.
Why alcoholic koH is used in test for saponification value in lipid?
To prevent formation of soap (by substitute the water with alcohol). But indeed KOH forms an ester with fatty acids. Explain a bit the role of alcohol please. Sometimes KOH is used to conjugate and Fatty acid. When lead to saponification and when to conjugation?
What do the processes of Saponification and esterification have in common?
Both saponification and esterification are chemical reactions involving the formation of esters. In saponification, esters are hydrolyzed by an alkali to form soap and alcohol, while in esterification, an ester is formed from a reaction between a carboxylic acid and an alcohol. Both processes involve the exchange of functional groups to create esters.
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.
Why does the use of aluminum containers interupt the saponification process, and what material would completely prevent the saponification process?
Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions).
Can a magnet create saponification?
No, a magnet cannot create saponification. Saponification is a chemical reaction that typically involves a base (like lye) with fats or oils to produce soap. Magnets do not play a role in this chemical process.

What are two products of saponification?
Ethyl Alcohol + Ethanoic Acid
What is kinetic of saponification?
Saponification is a chemical reaction between an ester and a base, resulting in the formation of a soap and an alcohol. The kinetic study of saponification involves examining the rate at which this reaction occurs under different conditions, such as temperature, concentration of reactants, and the presence of catalysts. By studying the kinetics of saponification, scientists can determine the reaction mechanism and optimize the process for soap production.
Why washing soaps are sodium salts?
Because sodium hydroxide is used in the saponification process of fats.
What happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH
Why is saponification reaction is considered to be the reverse of an esterification reaction?
saponification is considered to be the reverse process of an esterification reaction due to the fact that esterification is combining an alcohol and a carboxylic acid but a saponification is breaking apart the ester by adding an NaCl molecule (soap) to the chain of carbons.
