What property of tetraoxosulphate vi acid made it suitable for preparing trioxonitrate v acid

Yes

high boiling point pf HwSO4 compared to HNO3

yes

The property of tetraoxosulphate VI acid (also known as sulfuric acid, H2SO4) that makes it suitable for preparing trioxonitrate V acid (also known as nitric acid, HNO3) is its strong acidic nature.

To understand why sulfuric acid is suitable for preparing nitric acid, we need to know the reactions involved. The reaction between sulfuric acid and sodium nitrate (NaNO3) is as follows:

2 H2SO4 + 2 NaNO3 → Na2SO4 + 2 HNO3

In this reaction, sulfuric acid reacts with sodium nitrate to form sodium sulfate and nitric acid. The key role of sulfuric acid in this reaction is its ability to donate protons (H+) to react with nitrate ions (NO3-) from the sodium nitrate. This proton transfer from sulfuric acid to nitrate ions results in the formation of nitric acid.

Sulfuric acid is a strong acid, meaning that it easily donates protons. It is a highly acidic and corrosive substance that can react with various compounds and substances, making it a versatile reagent in many chemical reactions. Its strong acidic nature allows it to react effectively with sodium nitrate to produce nitric acid.

Therefore, the strong acidic nature of sulfuric acid is the property that makes it suitable for preparing nitric acid.
