KOH is used to prepare liquid soaps.
KOH is the reactant in this reaction:2 MnO2 + 4 KOH + O2 = 2 K2MnO4 + 2 H2O
Heat the flask on a steam bath.

It forms a precipitate called sodium chloride and barium hydroxide, which both are colourless.
12 J/3 moles = 4 J/mole. Thus, H of reaction in kJ/mole = 0.004 kJ/mole
When stearic acid is added to potassium hydroxide (KOH), it undergoes saponification to form potassium stearate and water. This reaction is commonly used in soap making processes. The reaction can be represented by the chemical equation: C17H35COOH + KOH -> C17H35COOK + H2O
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?
The balanced Saponification equation for trimyristin and KOH is as follows: C45H86O6 + 3KOH -----> C3H5(OH)3 + 3K+-C14H27O2 This is a very condensed formula... If I were you, I would suggest looking up the structural formula for trimyristin, which can be found at the link below, and then do the replacement reaction.
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.
Insoluble soaps are not likely to exist, they won't work when not IN water. For more you can trust on this: his process is called saponification: fat + sodium hydroxide -> Sodium salts of fatty acid (Soap) + glycerol
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.
The lard sample will require more KOH for complete saponification. This is because lard is a saturated fat, and therefore the molecules are more closely packed together. This means that there are more bonds that need to be broken in order to saponify the fat.
No , it is not human body reaction .
Soap is produced in the saponification reaction, where fats or oils react with a strong base, typically sodium hydroxide or potassium hydroxide, to form soap and glycerol.
Saponification takes place in places where fat is stored in the human body.
The catalyst needed for saponification is typically an alkali, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH). These alkalis help to hydrolyze ester bonds in fats or oils, leading to the formation of soap.
KOH + HCl -> KCl + H2O This is a neutralization reaction. You know because it produces water and a salt.
