How do you calculate lye solution?
Divide the amount of lye by 0.3 and then subtract the amount of lye from the result.
- (Amount of Fat) × (Saponification Value of the Fat) = (Amount of Lye)
- (Amount of Lye) ÷ 0.3 = (Total Weight of Lye Water Solution)
- (Total Weight of Lye Water Solution) − (Amount of Lye) = (Amount of Water)
How do you make potassium carbonate solution?
Production. Potassium carbonate is prepared commercially by the reaction potassium hydroxide with carbon dioxide: 2 KOH + CO2 → K2CO3 + H2O. From the solution crystallizes the sesquihydrate K2CO3·3⁄2H2O (“potash hydrate”).
How is potassium carbonate used in soap?
Potassium carbonate is most commonly used in soap making and is involved in other processes, including soaping fats in a way other than burning alkalis and then converting fatty acids to soap by neutralizing them with sodium or potassium or hydrate carbonate.
How do you make potassium hydroxide from potassium carbonate?
Potassium carbonate, if heated strongly, gives off carbon dioxide gas, producing potassium oxide. Reacting the oxide with water produces potassium hydroxide.
How much water do I add to lye?
The lye to water ratio of the lye solution is roughly 1 part lye to 2.3 parts water.
How do you use lye on a calculator?
To use a lye calculator, you input the oils you want to use, the amount of each oil you plan on using, and you can also specify if you want to superfat the soap or not. (Remember, that means you’ll leave leftover oils that help condition the skin and keep the soap from being too drying.)

What is the chemical formula for potassium bicarbonate?
KHCO3
Potassium bicarbonate/Formula
Potassium hydrogencarbonate (also known by archaic name potassium bicarbonate or potassium acid carbonate) is the inorganic compound with the chemical formula KHCO3. It is a white solid.
What is in potash?
Potash is an impure combination of potassium carbonate and potassium salt. Rock deposits bearing potash resulted when ancient inland seas evaporated millions of years ago.
How can I prepare potassium carbonate from pearl ash?
An alternative method, to obtain this compound is by treating it with carbon dioxide (CO 2) in the presence of an organic amine which results in potassium bicarbonate and on further calcination of KHCO 3 gives potassium carbonate. Pearl ash is non-combustible. When it comes in contact with skin, eyes, and respiratory tract can cause irritation.
What is the other name of pearl ash?
It is also called Carbonate of potash, or Dipotassium carbonate or Pearl ash. It is a dipotassium salt of carbonic acid. It is widely used in the production of glass and soap. Pearl ash is hygroscopic, deliquescent powder white in colour.
Is pearl ash soluble in alcohol?
Pearl ash is hygroscopic, deliquescent powder white. It is odourless and tastes like alkaline. It is readily soluble in water but insoluble in ethanol, acetone, and alcohol. It has a pH of 11.6. It is a primary component of potash.
How do you make potassium hydroxide carbonate?
1. It is prepared commercially by reacting potassium hydroxide (KOH) with carbon dioxide (CO 2 ): 2. An alternative method, to obtain this compound is by treating it with carbon dioxide (CO 2) in the presence of an organic amine which results in potassium bicarbonate and on further calcination of KHCO 3 gives potassium carbonate.
