How will Recover sodium hydroxide from lye?

Answer 1

Lye is another word for a strong alkali, and sodium hydroxide happens to be the most common. If you have lye in a water solution, there is no way you can get the NaOH out of it. But solid lye or solid drain cleaner provides the solid form of the product.
