Lye is one of those "common names" that, particularly when combined with adjectives, might mean a couple of different compounds.
The canonical lye is sodium hydroxide. However, potassium hydroxide has very similar chemical properties, and I've seen terms like "wood lye" that indicate it's actually the potassium compound instead.
"Caustic lye" is a new one on me; both compounds have common names that include the word caustic (caustic soda for sodium hydroxide, caustic potash for potassium hydroxide), so it might be either one.
If it's in a recipe for soap or something, it doesn't really matter all that much; as stated earlier, they have very similar properties and either will work.
Sodium hydroxide is the scientific name for caustic soda.
The IUPAC systematic name for NO2 is nitrogen dioxide.
The correct systematic name for SnF2 is tin(II) fluoride.
The systematic name of the compound CCl3F is trichlorofluoromethane.
I think it would be Azane .
Les Lye's birth name is Leslie Earnest Lye.
Reg Lye's birth name is Reginald Thomas Lye.
Sodium hydroxide is the scientific name for caustic soda.
The systematic name for IF3 is iodine trifluoride.
The systematic name for KCl is potassium chloride.
The systematic name of K2SeO4 is potassium selenate.
The systematic name for COSO3 is carbonyl sulfite.
The systematic name for ICI3 is trichloroiodomethane.
The systematic name for gypsum is calcium sulfate dihydrate.
Soda lye, known as sodium hydroxide Potash lye, a less common name for potassium hydroxide Chamber lye, urine
The systematic name of "cuclo" is not provided. If you provide the complete molecular structure, I can help you determine the systematic name of the compound.
The systematic name of barium chloride is barium dichloride.
