Answer for screen readers

The final answer is a base.

More Information

The NO3- ion is the conjugate base of the strong acid HNO3 (nitric acid), which makes it a very weak base in aqueous solution, having negligible effect on pH.

Tips

A common mistake is not considering the conjugate nature of ions when identifying acids and bases.
