Is sodium hydroxide bad for you?
Sodium hydroxide does not produce systemic toxicity, but is very CORROSIVE and can cause severe burns in all tissues that it comes in contact with. Sodium hydroxide poses a particular threat to the eyes, since it can hydrolyze protein, leading to severe eye damage.
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.

- Chlorine gas is also produced in this process. Solid sodium hydroxide is obtained from this solution by the evaporation of water. Principle — In castner-kellner method NaOH is prepared by the electrolysis of aqueous solution of NaCl (Brine).
- Sodium hydroxide is a corrosive chemical sometimes known as lye or caustic soda. It's chemical formula is NaOH. Sodium hydroxide is a strong base that can be dissolved in water.
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.
- Although potassium is the eighth most abundant element on earth and comprises about 2.1% of the earth's crust, it is a very reactive element and is never found free in nature. Metallic potassium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of molten caustic potash (KOH).
- Potassium Hydroxide is extremely corrosive and can be a hazardous irritant when exposure is at high levels. According to its Material Safety Data Sheet, it "May cause irritation. Contact of skin can cause irritation or severe burns and scarring with greater exposures."
- Identify each salt as acidic, basic, or neutral. The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Although the K + ion derives from a strong base (KOH), the NO 2 − ion derives from a weak acid (HNO 2).
