HPO4-2 is an acid and a base.
however when mixed with NO2- (Base) then HPO4-2 must be an acid.
The conjugate base of HNO2 is NO2-. When HNO2 loses a proton, it forms its conjugate base, nitrite ion (NO2-).
NO2 can act as both an acid and a base in water. When dissolved in water, NO2 can act as an acid by donating a proton to water, forming nitric acid. It can also act as a base by accepting a proton from water, producing nitrite ions.
HNO2 conjugate acid = one more hydrogen conjugate base = one less hydrogen
Ka= [H+][NO2-] [HNO2]
When you mix Nitric Acid HNO3 with Sulphamic Acid H3NSO3 you will get NITROUS OXIDE N2O , Sulphuric Acid H2SO4 and Water H2O
The conjugate base of HNO2 is NO2-. When HNO2 loses a proton, it forms its conjugate base, nitrite ion (NO2-).
NO2 is not a base. It is a nitrogen dioxide molecule which can act as an acidic gas when dissolved in water, forming nitric acid.

The name for NO2 is nitrogen dioxide. It is a reddish-brown gas with a sharp, acrid odor and is an important air pollutant contributing to smog and acid rain.
When you mix Nitric Acid HNO3 with Sulphamic Acid H3NSO3 you will get NITROUS OXIDE N2O , Sulphuric Acid H2SO4 and Water H2O
HNO2 => H^(+) & NO2^(-) are the ions present. NOTE Nitrous acid is ' HNO2' ; Nitric Acid is HNO3 .
Potassium Nitrate is a salt
The nitrate ion (NO3-) is a so extremely weak base that it will gain no proton at all from water.(That's why HNO3 is a so strong acid that it 'splits' off ALL its protons. in water there is no molecule HNO3 remaining.)
Nitrogen Dioxide-NO2 is also called as mixed anhydride.
NO2 is the polyatomic ionic compound nitrite Since it is bonded with hydrogen, this compound is an acid The correct name for HNO2, is therefore nitrous acid
