The strong acids


An acid $HB$ is strong if its proton exchange reaction with water (dissociation) producing the corresponding base $B$ $HB$ $+$ $H_2O$ $\rightarrow$ $ H_3O^+$ $+$ $B$ is complete

- Note the single arrow reaction     $\rightarrow$ - Eventual charges of $HB$ and $B$ are not shown in this general formula


Common strong acids

$HClO_4$perchloric acid
$HNO_3$nitric acid
$H_2SO_4$sulfuric acid
$HCl$chlorhydric acid
$HBr$bromhydric acid
$HI$iodhydric acid

Dissociation reactions of these strong acids: $HClO_4$ $+$ $H_2O$ $\rightarrow$ $ H_3O^+$ $+$ $ClO_4^-$ $HNO_3$ $+$ $H_2O$ $\rightarrow$ $ H_3O^+$ $+$ $NO_3^-$ $H_2SO_4$ $+$ $H_2O$ $\rightarrow$ $ H_3O^+$ $+$ $HSO_4^-$ $HCl$ $+$ $H_2O$ $\rightarrow$ $ H_3O^+$ $+$ $Cl^-$ $HBr$ $+$ $H_2O$ $\rightarrow$ $ H_3O^+$ $+$ $Br^-$ $HI$ $+$ $H_2O$ $\rightarrow $ $H_3O^+$ $+$ $I^-$
