The property of concentrated H2SO4 that makes it suitable for preparing HNO3 is its
boiling point
density
oxidizing properties
dehydrating properties
Correct answer is A
\(H_2SO_4\) acid has a high boiling point of 388°C. Due to its high boiling point, it is considered a non-volatile acid, so when sulphuric acid is reacted with salts of nitric acid eg \(NaNO_3\), \(HNO_3\) is displaced from its salt
