because most Na salts are soluble and most nitrate salts are soluble so there is no easy way to convert them to insoluble forms. Of course you have already pointed out that NaNO3 itself is quite soluble. Na can be QUANTITATIVELY determined if the amount to be determined is large enough. I don't have any first hand knowledge of its accuracy but in general I think you are on solid ground that quantitative determinations of Na are not easily done.

all sodium salts and all nitrates are completely soluble in water.
