Answer:

Add some silver chloride, lead chloride or calcium chloride to the solution. A precipitate indicates sulfuric acid.

Explanation:

The nitrates of those metals are soluble, but the sulfates are not. A precipitation (or maybe cloudiness in the solution) would indicate sulfuric acid. The nitric acid solution would remain clear, with no precipitate.
