People call HNO3 nitric acid. Strictly is it nitric(V) acid. OCR A state in their spec that if you ever see nitric (or sulfuric) then it is the common form: HNO3 (or H2SO4) - they will only include the numeral if there is an unusual oxidation number.
The original question says sodium nitrate(|||) nor sodium (|||) nitrate.
I’m confused now
I assume you meant "not" in your first sentence. Look at your post 11. You quoted someone saying sodium(III) nitrate and said that is exactly what you thought NaNO3 was.
