by adding AgNO3, ppt. is formed in h2so4 not hno3.
This reaction is:S + 6 HNO3 = H2SO4 + 2 H2O + 6 NO2
H2SO4 is needed to first react with HNO3 to give NO2
NaNO3 + H2SO4
When dilute nitric acid (HNO3) reacts with non metals (excluding H2, C, N2 and O2) it forms acid from that non metal. For example, if HNO3 reacts with sulfur (S) it gives nitric oxide, water and sulfuric acid (H2SO4). It only reacts with carbon to form carbon dioxide (CO2) instead of its acid. Some more examples: HNO3 + P --> H3PO4 + NO + H2O HNO3 + S --> H2SO4 + NO + H2O HNO3 + Se --> H2SeO3 + NO + H2O HNO3 + C --> CO2 + NO + H2O HNO3 + S --> H2SO4 + NO + H2O
Some examples: HCl, HNO3, H2SO4.

10S + 40 HNO3 → 10 H2SO4 + 40 NO2 + H2OS + 6HNO3 → H2SO4 + 6NO2 + 2H2OS + 4HNO3 -→ SO2 + 4NO2 + 2H2O
It is actually a mixture of very dilute H2SO4 and HNO3
