Question

In what physical state will $\mathrm{NaOH}$ be at room temperature? Explain.

Answer 1

Sodium hydroxide at room temperature:

• At room temperature Sodium hydroxide($\mathrm{NaOH}$) is a white, odorless solid commonly known as Caustic soda.
• It is a corrosive white crystalline solid that contains Sodium $\left({\mathrm{Na}}^{+}\right)$ and hydroxide $\left({\mathrm{OH}}^{-}\right)$ ions.
• Sodium hydroxide readily absorbs moisture and forms aqueous solutions which mean that Sodium hydroxide as a solid will lose its strength with time and becomes largely inert.

Therefore, $\mathrm{NaOH}$ will be a solid at room temperature.
