You can eat. Sodium hydroxide is nontoxic, soluble in water and clean after washing.

1, sodium hydroxide, chemical formula is NaOH, commonly known as caustic soda, caustic soda, caustic soda.

2. Sodium hydroxide is a white translucent crystalline solid. Its aqueous solution has astringency and satiny. Corrosive.

3. Solubility: extremely soluble in water, releasing a lot of heat when dissolved. Soluble in ethanol and glycerol. Deliquescence: Easily deliquescent in air. Water absorption: solid alkali has strong hygroscopicity. When exposed to air, it will absorb water molecules in the air, and eventually it will completely dissolve into a solution, but liquid sodium hydroxide has no hygroscopicity.
