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 in its solid state is deliquescent and has a strong affinity for moisture in the air. As a result, lye will dissolve when exposed to open air, absorbing large amounts of atmospheric moisture. As a result, lye will dissolve when exposed to open air, absorbing large amounts of atmospheric moisture.
The release of hydrogen gas stirs the mixture and improves the interaction between the lye and the materials clogging the drain. It's possible that pressure may build up inside the pipe, causing the hot, caustic solution to spurt out of the drain. Sodium nitrate reacts with hydrogen gas: Na + + NO 3 − + 4H 2 → NaOH + NH 3 + 2H 2 O. This ...
Other corrosive mixtures come as two-part cleaners that are mixed as they are poured in the drain opening. Inside the drain the two solutions react to release a gas, and surfactants trap the gas as dense foam. The intent of this foaming action is to coat the inside of the drain pipe to dislodge more of the substances that form the clog.
[6] [15] It is a white solid with the orthorhombic crystal structure. [16] Sodium hypochlorite can also be obtained as a crystalline pentahydrate NaOCl·5H 2 O, which is not explosive and is much more stable than the anhydrous compound. [6] [7] The formula is sometimes given in its hydrous crystalline form as 2NaOCl·10H 2 O. [17]
In physics and chemistry, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy. [1] [2] Most modern equations of state are formulated in the Helmholtz free energy.
Lye is a caustic chemical, usually referring to sodium hydroxide. Lye or LYE may also refer to: Places. Lye, West Midlands, a town in England;
Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO 3 − ), which is useful in several reactions carried out on industrial scales for the production of fertilizers , pyrotechnics , smoke bombs and other explosives , glass and pottery enamels , food preservatives (esp ...
