What is the purpose of sodium hydroxide?

Sodium hydroxide is used to produce soaps, rayon, paper, products that explode, dyes, and petroleum products. It can also be used in tasks such as processing cotton fabric, metal cleaning and processing, oxide coating, electroplating, and electrolytic extraction.

Why is sodium hydroxide used as a reagent?

Sodium hydroxide is widely used in biochemistry. It is a basic solution and has the ability to raise pH of chemical solutions, for example it useful for neutralization of acids.

Why is sodium hydroxide used in water treatment?

A: Sodium hydroxide is used in the treatment of drinking water to raise the pH of the water to a level that minimizes the corrosion. Raising the pH remains one of the most effective methods for reducing lead corrosion and minimizing lead levels in drinking water.

What is true with respect to sodium hydroxide?

Physical properties. Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition, and with a boiling point of 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol.

Does NaOH react with water?

Nothing, the sodium hydroxide will just dissolve in water. And free sodium ions and hydroxide ion are present in water. There isn’t quite a reaction. Sodium hydroxide (NaOH) is an ionic molecule so when it mixes with water is splits into Na+ and OH- due to the polarity of water molecules.

What happens when NaOH dissolves in water?

When sodium hydroxide (NaOH) dissolves in water, it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions). Each mole of sodium hydroxide that dissolves will produce one mole of sodium ions and one mole of hydroxide ions.

Is h2o an acid or base?

So, Is H2O an acid or base? Water(H2O) is amphoteric in nature means it can act as an acid as well as base, depending on what it is reacting with. But the extremely pure water is always neutral(neither acidic nor basic) since it contains an equal number of H+ ions and OH– ions and pH equal to 7.
