Why is sodium hydroxide so soluble in water?
When sodium hydroxide (NaOH) dissolves in water, it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions). It is very soluble in water and, like all gases, it’s solubility depends on the partial pressure of the gas.

What does sodium hydroxide do to water?
Q: How does sodium hydroxide work? 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.

Is sodium hydroxide dissolving in water a chemical change?
When sodium hydroxide dissolves in water the bond between the sodium and hydroxide breaks leads to the formation of ions. Any reaction associated with the breaking of bonds and leads to new products is known as chemical change. Thus, sodium hydroxide dissolves in water as a chemical change.
What is produced when sodium hydroxide reacts with water?
In soluble form sodium always occurs as Na+ ions. In what way and in what form does sodium react with water? A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction.
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 can react violently with strong acids and with water. Sodium hydroxide is usually sold in pure form as white pellets or as a solution in water.
