It is very soluble in water with liberation of heat. It also dissolves in ethanol and methanol, though it exhibits lower solubility in these solvents than does potassium hydroxide. It is insoluble in ether and other non-polar solvents. A sodium hydroxide solution will leave a yellow stain on fabric and paper.
Is NaOH a solvent?
Other names: Lye, Caustic Soda
Other anions: Sodium chloride; Sodium sulfate
Is NaOH a solution or solvent?
Sodium hydroxide is very corrosive. It is generally used as a solid or a 50% solution. Other common names include caustic soda and lye.
What type of solvent is NaOH?
These solvents can also serve as acids (sources of protons) and weak nucleophiles (forming bonds with strong electrophiles). They are most commonly used as the solvent for their conjugate bases. Hence NaOH has the highest basic strength in polar protic solvent.
Is NaOH soluble in water?

Why is NaOH soluble?
NaOH is a strong base. Strong means, in water it dissociates 100% into its ions Na+ and OH-, both of which are considered very soluble in water.
Is NaOH a salt?
Sodium hydroxide is derived from salt water (brine). It is most commonly manufactured by the electrolysis of brine, a salt (NaCl) solution. During this process the water (H20) is reduced to hydrogen gas (H) and hydroxide ion (OH). The hydroxide ion bonds with the sodium to form sodium hydroxide (NaOH).
Why is lye illegal?
It is also known as lye, although lye may refer to either potassium hydroxide or sodium hydroxide. Pure caustic soda is sold for making candles or soap. Impure caustic soda is found in drain cleaner. Because lye is used to make illegal drugs, it's harder to buy large quantities than in the past.
Is sodium hydroxide a liquid?
At room temperature, sodium hydroxide is a white, odorless solid. Liquid sodium hydroxide is colorless and has no odor. … It is used to make soap and as a main ingredient in household products such as liquid drain cleaners. Sodium hydroxide is usually sold in pure form as white pellets or as a solution in water.
Is NaOH hydrophilic?
NaOH is usually used before the addition of APES in order to make a hydrophilic surface. You can try RainX solution or DCMS solution (it is more toxic by the way) to make it become hydrophobic.
