What is the use of sodium hydroxide?
What are some uses of sodium hydroxide?
- It is major ingredient in drain and oven cleaners.
- It is used in chemical manufacturing, oil refining, hydraulic fracturing, water treatment and metal processing.
- It is used in the manufacture of fabric, plastic wrap, paper and soap.
Sodium Hydroxide is, however, a known irritant. Studies by the National Institute for Occupation Safety and Health found that this ingredient causes "Irritation eyes, skin, mucous membrane; pneumonitis; eye, skin burns; temporary loss of hair" and recommends that consumers prevent skin and eye contact.

Where is sodium hydroxide found?
Sodium hydroxide, NaOH, also known as lye or caustic soda, is an extremely caustic (corrosive and damaging to human tissue) white solid that readily dissolves in water. Sodium hydroxide is used in the manufacture of soaps, rayon, and paper, in petroleum refining, and in homes as drain cleaners and oven cleaners.
How is sodium hydroxide harmful to the environment?
The hazard of sodium hydroxide for the environment is caused by the hydroxide ion (pH effect). A high concentration in water will result in toxic effects for aquatic organisms e.g. fish.
What is the solute in sodium hydroxide?
A solution consists of a solute and the solvent. Solute is the dissolved substance and solvent is the substance in which the solute is dissolved. A solute can be a solid or a liquid. In NaOH solution, sodium hydroxide (solid) is the solute and water (liquid) is the solvent.
What makes Naoh?
Sodium hydroxide is a corrosive chemical sometimes known as lye or caustic soda. It's chemical formula is NaOH. It is an ionic compound, because it is made of a metal ion, sodium (Na+), that is attracted to a nonmental ion, hydroxide (OH-).
What is caustic soda and what is it used for?
Caustic Soda Lye is one of the most widely used chemicals in the industry. Caustic soda is a solution of Sodium hydroxide (NaOH) in water. It is a strong base with a wide range of applications in different industries. We produce caustic soda together with chlorine and hydrogen from the electrolysis of salt brine.
Is sodium hydroxide an acid or alkali?
Copper oxide is a base because it will react with acids and neutralise them, but it is not an alkali because it does not dissolve in water. Sodium hydroxide is a base because it will react with acids and neutralise them. It's also an alkali because it dissolves in water.
Some common bases as sodium hydroxide, ammonia and more
|Sodium carbonate (washing soda)||0.1 N||11.6|
|Sodium hydroxide (caustic soda)||N||14.0|
|Sodium hydroxide||0.1 N||13.0|
|Sodium hydroxide||0.01 N||12.0|
Potassium hydroxide, or caustic potash, is used in a wide variety of industrial applications. The major uses are in the production of potassium carbonate, potassium phosphates, liquid fertilizers, and potassium soaps and detergents.
What is the main use of calcium hydroxide?
It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation.
What are the uses of lye?
A lye is a metal hydroxide traditionally obtained by leaching ashes (containing largely potassium carbonate or "potash"), or a strong alkali which is highly soluble in water producing caustic basic solutions. Today, lye is commercially manufactured using a membrane cell chloralkali process.
Is Lye bad for you?
Lye is a very caustic chemical capable of causing serious damage. It can burn skin, cause blindness, and even cause death if ingested. And yet, this dangerous chemical is one of the main components of homemade soaps. Old timers will tell stories of how harsh lye soap is on the skin, but how well it cleans clothes.
Is sodium hydroxide a salt?
NaOH, or sodium hydroxide, is a very strong base, like everyone else is saying. However, it is NOT a salt. A salt results from the neutralization between an acid and a base. So if the NaOH were to neutralize with an acid like, say, hydrochloric acid (HCl), the resulting NaCl would be a salt.
How do you make lye?
To make lye in the kitchen, boil the ashes from a hardwood fire (soft woods are too resinous to mix with fat) in a little soft water, rain water is best, for about half an hour. Allow the ashes to settle to the bottom of the pan and then skim the liquid lye off the top.
How is sodium hydroxide is produced?
Sodium hydroxide can be made (with chlorine and hydrogen) using the chloralkali process. A solution of sodium chloride is electrolyzed and sodium hydroxide is made around the cathode, where water is reduced to hydrogen gas and hydroxide ion. The solution may splatter or boil.
