if we go through in inorganic compounds central element with highest oxidation state is maximum acidic in nature for example HClO4 >HClO3>HClO2>HClO,other is HClO4>H2SO4>HNO3>HNO2 ,SO3>SO2 ,N2O5>NO2 and many but if oxidation state is same than give preferance to electronegativity for example HClO4>HBrO4>HIO4 ,HOF>HOCl>HOBr>HOI ,IN SOME CASES ACIDIC STRENGTH ALSO DECIDED BY BOND LENGTH FACTOR For example HI>HBr>HCl>HF ,H2Te>H2Se>H2S>H2O

acidic nature of compounds depends upon how compound releases H+ in the solution for any organic compound as the -I effect or -R effect of compound increases acidic nature also increases for example ClCH2COOH is more acidic than CH3COOH because in CH3COOH there is +Ieffect of alkyl group whcich decreases acidic nature.always remember hydrogen bonding decreases acidic nature for ex.HCl is more acidic than HF and RSH is more than ROH.
