# Is sodium ion an acid?

As sodium ion has a 1+ charge and it can form the ionic compound NaOH with OH1-, hence it is a lone pair accepter (is this correct?). Therefore sodium ion should be an acid?

• Yes, it's a Lewis acid, but a weak one. – Mithoron Sep 15 '18 at 18:22
• But $\ce{Na+}$ isn't an acid in the Brønsted–Lowry theory, so it depends... – MaxW Sep 15 '18 at 23:33
