Well, all nitrates are soluble.........

Explanation:

And all sodium salts are soluble...and most sulfates are soluble. Barium sulfate, however, is reasonably insoluble

And should barium nitrate, and sodium sulfate be mixed in aqueous solution, a $metathesis$ $"metathesis"$ or $partner exchange reaction$ $"partner exchange reaction"$ should occur, and insoluble barium sulfate should precipitate. How do I know this? How else but by experiment? And 20 or so years ago I did the same experiment as you did.

$B a {(N O_{3})}_{2} (a q) + N a_{2} S O_{4} (a q) \to B a S O_{4} (s) ⏐ ↓ + 2 N a N O_{3} (a q)$ $Ba(NO_3)_2(aq)+Na_2SO_4(aq) rarr BaSO_4(s)darr + 2NaNO_3(aq)$

And we could write the net ionic equation, given that nitrate and sodium salts are all soluble......

$B a^{2 +} + S O_{4}^{2 -} \to B a S O_{4} (s) ⏐ ⏐ ↓$ $Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr$

None of this is a replacement for doing the experiment, and noting down your observations.
