Binary acids
E.g. HF, HCl, HBr, HI, H2S
The acidity of the haloacid: (HX; X = F, Cl, Br, I)
Series increase in the following order:
HF < HCl
< HBr < HI
(Going down a group it increase for binary
acids)
Oxo acids
Acidity depends oxo groups HClO4 ,
Acidity: HClO4>HClO3>HClO2>HClO
HNO3> HNO2
H2SO4 > H2SO3
