Answer 9

I agree, the answer would be D.

Here's the difference between an `acid` and a `base`

Acid: a compound that contains hydrogen and produces Hydrogen ions, H+, when it breaks apart in solution

Base: A compound that has OH in its formula and produces hydroxide ions, OH-, when it breaks apart in solution.

Based on this brief explanation, (NaOH) would be considered a base (option D) because...
1. The formula contain OH
2. It produces hydroxide ions
