Question

rank in order of acidity HNO3, NaNO3, HNO2, NaNO2

Answer 1

As you know, \(NaNO_2\) is basic, \(NaNO_3\) is neutral, and \(HNO_2\) is less acidic than \(HNO_3\). Therefore, the correct order is \(NaNO_2<NaNO_3<HNO_2<HNO_3\).

Answer 2

But how did you arrive at that? What is the logic? Can you explain the underlying concept tiny?
