What Is The Difference Between Using Sodium Hydroxide And Potassium Hydroxide In Making Soap
Potassium hydroxide on the other hand is more soluble in water so its more suitable for liquid soap. The metal in potassium hydroxide is heavier than the metal in sodium hydroxide.

Potassium hydroxide is more conductive than sodium hydroxide.
What is the difference between using sodium hydroxide and potassium hydroxide in making soap. On the other hand potassium hydroxides integrated to produce liquid soaps which are comparatively mild. Potassium has 19 protons and sodium has only 11. Well sodium hydroxide will react with the oils causing the molecules to be denser and tighter as compared to potassium hydroxide therefore its more suitable for solid soap.
Potassium hydroxide is somewhat more corrosive than sodium hydroxide. If you dont use sodium hydroxide or potassium hydroxide another compound used in soapmaking you cant make soap. Sep 07 2012 Sodium Hydroxide is more commonly known as lye or caustic soda where Potassium Hydroxide is known as potash.
Sodium Hydroxide NaOH is a royal pain in the butt to get it to dissolve in Methanol. Weve laid out some great lye choices so you can get your soap-making on. Even though their solubility in room temperature water is about the same products made with potassium hydroxide exhibit a greater solubility especially as you increase.
Sep 08 2020 Lye technically refers to sodium hydroxide which is ideal for soapmaking. However the limited solubility of sodium hydroxide in organic solvents means that the more soluble potassium hydroxide KOH is often preferred. Jan 13 2020 Potassium hydroxide is slightly smaller than sodium hydroxide which means it cuts through oil molecules faster than sodium hydroxide.
The sodium hydroxide is blended in hand soaps to fight the germs and clean the hand skin. It just LOVES to keep on hanging aroundin solid form. Soapmaking is a ton of fun and you dont want to miss out.
This makes potassium hydroxide a great choice for soaps that need to remove caked-on. Apr 06 2015 Molecular weight of potassium hydroxide is higher than that of sodium hydroxide because potassium is in period 3 while Sodium is in group 2 in the periodic table. Jan 23 2018 Potassium hydroxide and sodium hydroxide are strong bases.
Youll just have a big gooey mess. Youll just have a big gooey mess. However potassium hydroxide and other metal hydroxides are primarily alkaline and can be used in the soapmaking process.
Another difference is that potassium hydroxide is more soluble in water then sodium hydroxide 121 g of potassium hydroxide will dissolve in 100 ml of water compared to only 100 g of. When lye is added to water not the other way around it produces an exothermic reaction which means it gets very hot very quickly. The main difference between Potassium hydroxide and Sodium Hydroxide is that Potassium hydroxide has a potassium cation and a -OH anion whereas Sodium Hydroxide has a sodium cation and OH anion.
Sometimes NaOH is preferred because a smaller quantity as compared to KOH serves the purpose. Manufacturers usually prefer sodium hydroxide over potassium hydroxide because it is cheaper. The hand soap includes sodium hydroxide while the main ingredient used in the body wash is potassium hydroxide.
Both are hydroxides of alkali metals. 7 rows Soaps made using sodium hydroxide are harder often bar soaps whereas potassium. Potassium Hydroxide KOH however will begin dissolving almost on contact with methanol and dissolves extremely fast by comparison.
Both are used to change fats into soap in a process called saponification. Eye exposure to concentrated sodium hydroxide or potassium hydroxide solutions can cause severe eye damage and possibly blindness. Potassium has an atomic weight of 3910 and sodium has an atomic weight of 2299.
Sodium hydroxide can be used for the base-driven hydrolysis of esters as in saponification amides and alkyl halides. Contact with even dilute solutions will also cause skin irritation and injury the severity of which will depend on the duration of contact. Typically you will get a harder soap from sodium hydroxide than from potassium hydroxide.
This weight difference reflects the difference in the number of protons in each metal. The biggest difference between them is the cost because the cost of NaOH production from sodium chloride common salt which is quite inexpensive can be around ⅓ of the cost of. Electrical conductivity.
