The reason you can't find this anywhere is because there isn't really a test for Na+ like there is for Cl- or (SO4)2-. This is because Na+ salts are so soluble in water they rarely form precipitates. The best way to identify Na+ is with a flame test. Dip something such as a nichrome wire into the solution and then hold over the flame and observe the yellow flame.
