That statement is incorrect. Sodium hydroxide (NaOH) is not deliquescent. Deliquescence refers to the property of a substance to absorb moisture from the surrounding environment and dissolve in it, forming a solution.

While sodium hydroxide is a highly hygroscopic compound, meaning it readily absorbs moisture from the atmosphere, it does not dissolve completely in the absorbed water. Instead, it forms a concentrated solution. NaOH is commonly used as a desiccant, meaning it can absorb moisture and remove water vapor from the air. This property makes it useful in various applications such as drying gases and controlling humidity.
