Understanding Sodium Hydroxide Properties

The video explores whether sodium hydroxide (NaOH) is ionic or covalent. Sodium is a metal, while oxygen and hydrogen are non-metals, making NaOH an ionic compound. The video explains the charges on sodium and hydroxide ions, highlighting the ionic bond between them. It also discusses the covalent bond within the hydroxide ion itself. Ultimately, NaOH is confirmed as an ionic compound.
