HNO2 conjugate acid = one more hydrogen conjugate base = one less hydrogen
HNO2 is a weak acid.
Acid base pairs differing ONE proton (H+) are called conjugate acid-base pair.Examples:H3O+ and H2OH2O and OH-NH4+ and NH3HBr and Br-HNO2 and NO2-H2SO4 and HSO4-HSO4- and SO42-HOCl and OCl-(In order of 'acid and base' respectively)
HNO2 is nitrous acid, a weak acid.
Acid + base conjugate base + conjugate acid
HNO2 conjugate acid = one more hydrogen conjugate base = one less hydrogen
The anion NO2- is called Nitrite ion. It is the conjugate base of unstable Nitrous acid(HNO2)
HNO2 is a weak acid.
Acid base pairs differing ONE proton (H+) are called conjugate acid-base pair.Examples:H3O+ and H2OH2O and OH-NH4+ and NH3HBr and Br-HNO2 and NO2-H2SO4 and HSO4-HSO4- and SO42-HOCl and OCl-(In order of 'acid and base' respectively)
HNO2 is nitrous acid, a weak acid.
Acid + base conjugate base + conjugate acid
NH2- is the conjugate base of ammonia.
The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
The conjugate base of water is OH-.
The conjugate base of H3PO4 is H2PO4.
PO43-
The conjugate base of H2CO3 is HCO3-. Nope, itsHSO3-
