Ethanol is added to hasten saponification.
it is formed in saponification process.
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
Because sodium hydroxide is used in the saponification process of fats.
what happen when fatti acid react with the NaOH
The basic process is called fermentation.
Saponification is not applied to pure stearic acid; stearic acid esters are used.
Thymol is a good catalyst in saponification. I personally used it during chem prac class :)
Saponification is a process that makes soap. It usually involves mixing a strong base with a triglyceride such as fat or oil. The lye soap that was used by many people in frontier areas was made by mixing ashes from burned wood with tallow; the ash provided the lye (sodium hydroxide), the tallow provided the fat.
ethanol is used in alcohol
most "absolute" ethanol used in the lab is 95% ethanol by volume,this is due to the fact the ethanol is very miscible with water so its difficult to remove all the water that is present in the atmosphere,it is possible to get 100 alcohol but it is an awkward process and generally 95 does the job just fine
KOH is used to prepare liquid soaps.
Potassium hydroxide is used to prepare only liquid soaps. Soaps resulted from the saponification of fats with KOH are liquids or viscous. Soaps resulted from the saponification of fats with NaOH are solids.
