Sodium hydroxide is an ionic compound with the chemical formula NaOH. It is typically referred to as Sodium hydroxide or lye.

It is difficult to have a "word equation" for a single compound. However, we can use a word equation to represent the formation of sodium hydroxide:

Sodium + Water → Sodium Hydroxide + Hydrogen

This word equation represents the chemical reaction between sodium (Na) and water (H₂O) to produce sodium hydroxide (NaOH) and hydrogen gas (H₂).
