Whether something is acid or base the strength of that solution is measured by the pH scale. 0 (zero) is the most acid and 14 is the most base. distilled water measures 7 and is completely neutral. Ammonia is an example of a base and is usually measured at a pH of 11.6. So the answer to your question is that an acid has a positive pH. There is no such thing as a negative pH.
