Sodium Hydroxide is an inorganic chemical that at ambient temperature appears as a white crystalline solid. It's also called "caustic" because of its strong basic nature, which releases a lot of heat when combined with water or neutralized with an acid. Its solution is very corrosive to metals and can cause severe irritation to skin tissues, eyes, and mucous membranes upon contact. When 25 g pure Sodium Hydroxide is added to 75 mL deionized water, it makes up the 25% (w/v) solution of Sodium Hydroxide. The Analytical Reagent Grade of chemicals has a high purity and is best suited for analytical purposes. They are important for research applications because of their results that are consistent, trustworthy, and reproducible. In the United States of America (USA), Lab Alley sells its high-quality items online at laballey.com. For industrial, commercial, and research needs, Lab Alley strongly recommends its Sodium Hydroxide, Analytical Reagent Grade, 20%.

How Do You Make A 20% NaOH Solution?

Assuming your 20% is weight on weight, just add 80 grams of water (80 mL at 20 degrees Celsius) to 20 grams of NaOH. You'll have [(20g NaOH) /(20g NaOH+80g water) ]*100 ==> 20g NaOH every 100g of solution. Read more here.

About Sodium Hydroxide

Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na⁺ and hydroxide anions OH⁻ .

At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive. It is generally used as a solid or a 50% solution. Other common names include caustic soda and lye. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting. It is commonly present in commercial drain and oven cleaners.

Sodium Hydroxide Uses

Sodium hydroxide is an ingredient in drain and oven cleaners. Sodium hydroxide is used in chemical manufacturing, oil refining, hydraulic fracturing, water treatment and metal processing. Used in the manufacture of fabric, plastic wrap, paper and soap. Sodium hydroxide is used in salt spray testing where pH needs to be regulated. Sodium hydroxide is used to manufacture many everyday products, such as paper and aluminum. Sodium hydroxide has been studied for its use in the treatment of prion disease (as occurs in mad cow disease and kuru).

Sodium Hydroxide Hazards

Sodium hydroxide is very corrosive. It can cause irritation to the eyes, skin, and mucous membrane; an allergic reaction; eye and skin burns; and temporary loss of hair. Workers may be harmed from exposure to sodium hydroxide. Read more here.

Sodium Hydroxide pH

Sodium hydroxide has the formula, NaOH and is also known as caustic soda or lye. It is extremely alkali and has a ph of 12. It is one of the strongest alkaline chemicals. It is very caustic and when in contact with the skin, can leave burns.
