Definitions for "NaOH"
Keywords:  caustic, hydroxide, soda, soap, sodium
Abbreviation/acronym — Chemical symbol for Sodium Hydroxide, aka caustic soda. Sodium hydroxide is used to produce hard bar soaps.
Sodium Hydroxide, lye, caustic soda (Red Devil Drain Cleaner). A metallic base. Strongly alkaline and extremely corrosive. Mixing with fluids usually causes heat, and can create enough heat to ignite flammables (such as methanol), so add slowly. "anhydrous sodium hydroxide" is one of the main reactants in the manufacturing process. Anhydrous means it's dry, and water turns biodiesel into soap, so this product needs to be stored in an airtight container to prevent NaOH from absorbing water and CO2 from the air.
