Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Lye is a hydroxide, either sodium hydroxide or potassium hydroxide. The word lye most accurately refers to sodium hydroxide (NaOH), [ citation needed ] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
Alkaline drain openers primarily contain sodium hydroxide (lye) and some may contain potassium hydroxide. They may appear in liquid or solid form. Solid formulations of corrosive alkaline drain cleaners are composed of a caustic substance (often sodium hydroxide or potassium hydroxide), aluminum particles, and 'additives.'
Originally, it was simply a liquid lye (sodium hydroxide). In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite . Sodium hypochlorite is used in low (5%) concentration as laundry bleach and in higher concentrations as a swimming pool disinfectant.
A much older form of portable toilet chemical is lye. Lye was used during the old "wooden outhouse days" to prevent odors. After a person is done using the portable toilet they would sprinkle a bit of lye into the holding tank. [citation needed] Lye can be dangerously corrosive to skin, and is rarely used today.

Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the ...
Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali.Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis.
