Question

what is saponification reaction ? with reaction
what are micelles?

Answer 1

C2H5OH + CH3COOH → CH3COOC2H5 + H2O
Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification process.
A micelle or micella is an aggregate of surfactant molecules dispersed in a liquid colloid. A typical micelle in aqueous solution forms an aggregate with the hydrophilic "head" .

Answer 2

Usually, saponification is a process by which
triglycerides are reacted with sodium or
potassium hydroxide (lye) to produce glycerol
and a fatty acid salt, called 'soap'.
