The final aqueous alcoholic material can usually be disposed of with the solvent waste. Waste sodium is readily destroyed with 95% ethanol.
Sodium is stored under kerosene because of its high chemical reactivity with almost all of other elements (for example oxygen from air which oxidizes it instantly). Therefore the answer to the second part of the question is: no you can not store sodium under alcohol because it will react with it.
In many cases sodium hydroxide can be re-used in a process as a substitute to a commercial chemical product. Sodium hydroxide can not be recycled when it has high metals content or organic contaminants. When transported it will still be considered a hazardous material but not a hazardous waste.
Sodium is one of the alkali metals, a group of famously reactive elements. Because sodium is so reactive, it is rare in its pure form, which is solid at room temperature but soft enough to cut with a knife. The reaction generates heat, which melts the sodium, and because hydrogen gas is flammable, it ignites.
Reaction with air, water, and hydrogenSodium does not react with nitrogen, so sodium is usually kept immersed in a nitrogen atmosphere (or in inert liquids such as kerosene or naphtha).
Sodium hydroxide solutions used have to be disposed as hazardous waste, in the appropriate basic container.
Pure sodium metal is extremely hazardous. Our air contains enough moisture (water) in it to react with the sodium metal. Sodium metal reacts violently with water and can explode. Even our hands contain some minor moisture that sodium can react with thus burning our hands.
Why is chlorin and sodium dangerous in pure form? Sodium is a metal. It interacts strongly with water to produce hydrogen gas and heat. In large quantities it can cause a fire.
Metallic sodium is priced at about 15 to 20 cents/lb in quantity.

sodium is a very reactive metal. it reacts so vigorously with oxygen that it can catch fire when kept in the open. hence to protect it and to prevent accidental fires, it is kept immersed in kerosene. so it should be handled with care.
Reactive metalAtoms share electrons with other atoms in order to bond, and a single electron dangling out on the edge is simply too tempting to pass up, molecularly speaking. As a result, sodium and the other alkali metals are so reactive that they're never found alone in nature.
In the Lab, sodium is mainly used as a desiccant for organic solvents (typically Toluene and THF). Sodium is stored in the form of chunks kept in mineral oil in a sealed container in a ventilated cabinet, and as a dry metal in a sealed container in the glove box.
Answer Expert VerifiedUsually, non-polar solvents like kerosene are used for storing alkali metals or substances. Benzene is a polar solvent which reacts with sodium or Potassium very vigorously. It is very expensive, has a low boiling point, and is very toxic too. Since it has low bp, it can easily get evaporated.
Potassium must always be stored under an inert atmosphere. Even when kept under mineral oil, a yellow coating of potassium superoxide may formafter prolonged storage if oxygen is present in the headspace of the container.

Sodium is one of the highly reactive alkali metals. In its pure form, the soft, shiny metal reacts in water to form sodium hydroxide and hydrogen gas. Oh, and lots of heat—enough that the hydrogen gas ignites. The mutual repulsion of those positive charges rips the metal apart, and it blasts outward in tiny needles.
Sodium at standard temperature and pressure is a soft silvery metal that combines with oxygen in the air and forms grayish white sodium oxide unless immersed in oil or inert gas, which are the conditions it is usually stored in.
In chemistry, a salt is an ionic compound which is made up of two groups of oppositely charged ions. The salt we put on our fries is actually sodium chloride and is made up of a Na1+ (that's our metal) and a Cl1- (our non-metal). Often you will see this written as Na+ and Cl- (the 1 is dropped), or simply NaCl.
Sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth's crust.
Sodium is the sixth most abundant element on Earth. It is never found in its pure form because it is so reactive. It is only found in compounds such as sodium chloride (NaCL) or table salt. Sodium chloride is found in ocean water (salt water), salt lakes, and underground deposits.
Group 1A — The Alkali Metals. Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
The Castner process is a process for manufacturing sodium metal by electrolysis of molten sodium hydroxide at approximately 330 °C. Below that temperature, the melt would solidify; above that temperature, the molten sodium would start to dissolve in the melt.
Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn't react with kerosene.
Is Sodium (salt) in drinking water a concern? Sodium is essential for normal functioning of the human body. It can be found in all body tissues and fluids, and it is not generally considered harmful at normal levels of intake from combined food and drinking water sources.
sodium (Na): Sodium element is present in group 1 due to presence of one valence electron. It has a large atomic size, because of all these reasons sodium metal is a soft metal. Moreover, the metallic bonding in sodium is not strong, hence it can be easily cut.
When sodium is dropped in cold water, it reacts explosively and burns with a golden yellow flame. The reaction is exothermic and vigourus. It form sodium hydroxide with the liberation of hydrogen gas.
Sodium is absorbed from the gastrointestinal tract, always bringing water along with it. It is the major mineral in plasma, the fluid component of blood, and in the fluids that bathe the body's cells. Without enough sodium, all these fluids would lose their water, causing dehydration, low blood pressure, and death.
The reaction is strongly exothermic, and the heat generated ignites the hydrogen gas. A small piece of sodium will will burst on the surface of water with a hydrogen flame under and around it. Sodium metal reacts rapidly with water to form a colorless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2).
Sodium reacts with the oxygen in air to form an oxide called the sodium oxide, and traces of yellow sodium peroxide. Therefore, the sodium metal should be immersed in kerosene oil, if it is kept open it reacts vigorously with oxygen and the moisture that is already present in the air and thus catches fire.
